I've never seen a product show so much of how it's made. That alone sells me on it. Well, how cool it is helps, too!
when these go up, i will buy tf out of them
i'd love one as well
@@antimattermemes3491 ur wallet tho :
will buy one

Hey there! I was a knife engineer in a previous job. Yes, a knife engineer, or rather, a precision edge engineer. I worked for a company that made all sort of knives. Everything from tree chipper blades, to scalpels. We did alot of blades similar to yours and had the exact same problems.
We typically had our blades belt ground instead of hardmilled for the edge. But sometimes we would stone grind blades. We sometimes would have as much of the material removed before hand as we could, without warping the material. Then heat treat and temper. And then final bevel. If we had warpage issues in heat treat. We would put a slight bow in the opposite direction during heat treat to counteract the warpage we would get later on. We would have a fixture table made and just slip shims underneath.
Even further, depending on our process, we would use the fixture plate in our grinders. But only for a straight blade. And we would flood grind these on large Mattison grinders. We could hold +/-.005 on parts 48" long and 1/32" thick. But maybe you could try that for hard milling since you have 3D capabilities.
If you wanted to get really fancy, the amount of material you remove would directly correlate with the warpage. If it's consistent enough, you could remove material strategically to counteract warpage.
If all else fails. We would typically peen the blades straight. But that is truly an art and very difficult to master.
In my experience, 440C was a much stabler material than A2 and D2. M2 was the most thermally stable and least prone to warpage on thinner blades.
I was about to suggest 440C. Its frowned upon because its not high end but I think for a novelty item like this it would be perfect.
I mean, I just stumbled on this video and I will buy one if I can afford it.
I don't need performance scissors, I'll probably never cut anything with it. And I am an ok flipper at best. I just want it as a cool innovation.
I'm curious if heat treating strain relief would be an option for blades? You basically reheat the metal to about 50 degrees c under the tempering temperature and hokd it there for an hour or two then allow to slowly cool either by air or in an oven that has been turned off.
I've done this for home brew parts before but never with a blade. In my case, I used a welding blanket to slow the cooling down. From there it was just some light sanding and polishing. I ended up with quite a bit of discoloring and some scale because I didn't hsve a way to use an inert gas, but dimensional accuracy on two ends was what I was after.
I distinctly remember an informative documentary where a guy used a neutron star in space to forge an axe blade to perfection. I have a vague memory of Kyle Hill hosting and/or featured in the show, so maybe ask him?
If you really want no warpage you can always do a stress relief and use PM steels. Due to the really uniform structure the warpage should be minimal to Zero.
@@Parpyduck I believe we watched the same doc, and that axe was cast, not forged.
Seriously, it has been a really fun experience watching your journey. Learned a lot about the prototyping process and how you went from that to a tangible design. I can’t wait to see the final product!
I’m quite surprised on how much he is improving The past few months
No I’m Elliott
been here since day one and can’t wait too
ive been following since episode 2 and im def gonna buy one when there ready
I can’t wait to try and buy these and have them be sold out already! I have been watching for a year now and the progress is amazing!
Dont know how I came across this video and I ended up watching the whole thing.
The amount of hard work and dedication it took this person trying to finalize his own tool was amazing and then the amount of time and creativity it took him to film and create this masterfull piece of video is just admirable. *****
same i saw the video and watched the wholl video
@@ITS_Syne wow, you guys watched an 11 minute video? no fucking way you watched the WHOLE thing?? dude you guys are awesomeeeeeee!!!!!!! want an award?
This is the video that was suggested to me that lead me to subscribe and binge watch all your videos from the start. WORTH IT. I highly encourage everyone to watch from the beginning. it didn’t take me long to finally catch up and rewatch this video.
I'm not really all that into Balisongs, but I cannot wait for the opportunity to buy a pair of these! Thank you for letting us all follow along and learning from your creative process, and for your dedication to perfection.
Yeah a folding knife only needs one handle. Folding scissors obviously only needs two handles. This just makes sense
any idea how much its gonna cost ?
@@DarkIzo Probably a lot, unfortunately
Never seen someone be so open with their failures and successes when making a product before. Keep up the good work!
Any engineer should be just as open. Nobody is perfect and there is always something to learn or improve upon
We need more people like you; people who really care about the details of the final product. Your conviction to high quality is truly admirable!
thats exactly what ive been thinking like i would have called it good at episode 3
I lust your name.
There are times when the recommendations are truly spot on, and this time is definitely one of them. Now I've got a lot of catching up to do.
I loved the 2 second mention of the faster print settings then being able to immediately find a link to the video in the description, like no messing around looking through 400 links to all your social media with the one I'm looking for mixed in, or searching it up myself. The link is just there.
Thank you very much, also great video and great idea for scissors, I could see these being super fun and genuinely very useful, I'd love to buy a pair
This is going to be a Premium Balisong when its completed but its a work of art at this point.
I know if I buy product like this it's gonna be high quality when someone makes 28 episodes about mechineing tolerance.
I'm so hyped for them to finish
This video just surfaced in my recommendations, and I'm glad it did. As someone who has manufactured custom parts for high performance cars using a lot of different vendors and fabricators, I can sympathize with a lot of what you're going through. It was your attention to detail and the array of tools that you have at hand that impressed me the most. Your in-depth explanation and presentation remind me a lot of Clickspring. Great video!
Apt comparison. Clickspring is great and so is this guy.
I have no idea about what's going on, but I couldn't help but stay and watch, appreciating the dedication and effort being put into creating a quality product.
A guy making a butterfly knife with two blades instead of one, and he’s been working on it for almost 3 years
I really like this, showing the struggles and mental process for finding the problem in the process and perseverance.
It's always a good day when there's a new baliscissor video. They look amazing more and more like a finished product with each video. I can't wait to place an order. Keep it up!
Have you thought about using your surface grinder and flood coolant to bevel the blades? Could machine or 3D print a fixture to orient the bevel correctly, and could even batch grind the blades. Appreciate you making such in depth videos! Really fun to watch.
Was just about to comment this
I missed a lot of the previous installments on this project, so I don't know if this was covered, but I wonder why he chose hard milling over flooded surface grinding. The surface grinder would be my first suggestion also.
That's a brilliant idea, it would be so much faster and cheaper, once the fixture is dialed in.
@@nefariousyawn there are definitely good reasons to hard mill, especially in a one man shop production environment, but very interested to see if the tormach grinder can handle flood coolant, and if that would keep it cool enough
Yeah, I don’t know much about making things out of metal in general but I also wondered why he is machining the bevel instead of grinding it, I suppose there might be a good reason? I don’t think there’s any harm in trying tho lol
As stated in the video" Shocking the tool with coolant decreases the life of the tool..." If you are machining without coolant during the whole program, then flood it with coolant afterwards, that can shatter that type of tooling. Running with coolant during the whole program is better for chip clearing and cooling than air. Flood coolant is best for chip clearing, but the air nozzle you had at first looked like you could run coolant through it and make it a mister, which would be good cooling, chip clearing, and even for filming
The warp in the blades would be a heat related issue. It's the sharpness of your tool, the amount of coolant used, the speed of the cut and the amount of material removed per pass all adding up wrong for your particular use case. The only way to solve this would be to cut much slower or replace the tool head more frequently. Another possible way to solve this would be to machine the material before fully hardening it and then hardening the pieces in a press or mould that would restrict too much movement/correct the warp. The material is less likely to snap when correcting the bend before heat treatment and the heating process would likely fix the warp. I know some people use a bucket of sand or a few vices to correct/hold the shape of a blade while heating them for the final temper, i'm sure the same could be done for the initial heat.
Such a fantastic and simple idea. The process of development really sells the product too. That logo is genius as well combining butterfly with scissors bravo!
What if you made your blades slightly over thickness and surface ground the other side to counteract the stresses from hard milling the bevel? Induction hardening only the very edge might also be worth a look, the bulk material of the rest of the blade self-quenches, it could be a much faster process than the oven, and might even remove the need to hardmill at all, but it would be an entirety new thing to figure out
Hardening only the edge might be a good idea but could also introduce warping. I mean think about Japanese swords. They get their curve from selective hardening. It wouldn't be as extreme on such a small scale, but in this case, precision is kind of important
I've watched this series from the beginning and never really had any intention of actually buying a pair. But these recent videos, especially this one, have convinced me to pick one up. I'm hyped for the launch!
Ditto.
I’d finish mill the blades un heat treated. Normalize to reduce stress. Then heat treat. This is what bladesmiths do with blades we forge or we grind, as it means less warping during the quenching of the blades. Changing your steel may help as well depending
Yeah I was going to mention normaloz8ng before heat treating but I just don't know enough about it to be sure if that's common or not.
@@Gkitchens1 if you don’t want your steel to warp it’s a very good idea. Now my experience in stock removal is VERY small. I forge my blades mostly to shape and grind only a little bit. But I do know that you can get warps if you grind a blade with to much stress in it. So you normalize to both reduce stress, and in some ways make it softer. If your feeling it (and have the equipment) you can fully anneal it and then grind it.
Bro, speaking as a Xray pipeline Welder, Metalworker, and a basic bench hand, your work is spectacular. I admire this, especially since I am a balisong freak.
This is why i love baliscissors cuz the tricks you can do with them are amazing
i encounter this phenomena when turning "thin" stuff on a larger scale. The surface gets so hot you get thermal expansion, and the heat also hardens the material at the same time somewhat and fixes the thermal expansion, causes tension in the material and warps it. And this is with extremely hard materials like Safurex. The soft metal you use suffer from it way more, unless you are willing to use 1 new tool per blade, you cant CNC machine the finished product. You need a grind the material away with coolant.
I’m new to CNC machining and was looking for a comment like this to see if anyone agreed with me on the visual diagnosis. It’s crazy how the coolant is warping it so bad. .045 is pretty big!
Grinding was also my first thought, it would keep the tool colder, and besides, its a proven way of tooling blades. Nevertheless I loved his approach from a 'different angle'
Need to press evenly fresh out the furnace after hardening . Placing it on 1 side of a cold plate before pressing down with the other plate means 1 side of the blade is losing significant heat before it's being pressed which is literally what's causing the warp. This being a year old video, I'm sure he's figured that out by now.
Looking great! Can't wait to get a few of these in my hands. Already have at least 2 or 3 gifts planned with these!
I am absolutely blown away! I've been following this project for a little while now and have thoroughly enjoyed being along for the journey. As a result of this channel and a few others I started working as a CNC Machinist apprentice 6 months ago and have never been happier. Keep up the great work and I look forward to buying my pair once they're finally released.
back in the late 70s early 80s the Baliscissors were my fidget toys.. lol. i played and practiced for hours with both hands. from like 8-9 to about 14-15 years old i missed with them. I'm 54 now and i bet i still have slight muscle memory for flippin them. i was throwing spyrolles with a football just last week play catch with my grandkids and son. but i was throwing and catching a football at 5, i built a lifetime of muscle memory i through the football so much as a kid and teen. thanks for the vid and bringing back a good memory.
Wow. This glimpse at just how much R&D goes into the production of an object I might otherwise take for granted really deepened my appreciation for all of the knives/tools I own.
Just stumbled upon this video. Never been interested in balisongs, but I would buy one of these just out of appreciation for how much work went into it (and b/c it's kinda sick af) 👍🏼
6:00 You can reduce the belt wear issue if you add a slope to the back side of the fixture (or to the platen) so that the belt is traveling at a slight angle to the blade. It'll also make them sharper to have the grind texture in a direction that creates micro-serrations along the cutting edge.
I have always wondered why the iterative process of getting a product ready for manufacture took so long and was so expensive. I learned a lot about that process from this video actually.
I am super impressed by the product and could see myself buying one. I've had this video open in another tab for the better part of a week, never quite getting around to it. Obviously I saw the title, but when you did a little demonstration in the beginning of the video, my jaw dropped a little. Not a hyperbole, it really wowed me, it's just one of those ideas like "how has no one thought of this before? It's just incredible." I feel like new inventions are so specific these days, and you are one of the few contemporary persons who managed to invent something that feels like it should have been an obvious development on two other inventions. Super impressed.
I cant wait to see when these are finished
It feels so close I can taste it. (Although I do not advise ingesting aluminum 😛)
Keep plugging away!! You are getting close and they are looking great!!!!!! I can't wait to buy one from you! Thank you, Cory
It's great to see not only the process, but also the failures. It's realistic and amazing to see the improvements and techniques that you use to solve the issues.
As an industrial designer, I can say that this is how a real project looks like.
THEY ARE LOOKING SOOO GOOD!
tumbled is definitely the way to go, it looks so clean
when you showed that animation of the engraving i actually think it looked really cool how it it was only partially engraved. i think it had an awesome feel, kind of like crystalization that hasnt finnished yet
I watched you first video I feel old that it’s been three years I can’t believe you came all this way to make Baliscissors I support you 💪💪💪💪
Just found this video on TH-cam. I am amazed at the quality of the product and how well it works, also the amount of planning and reworking you have had to do. You have done an incredible job. Well done.
This series has taught me a lot and it’s also just been great to just watch
I've been dying for these since the first episode dropped! Back then I worked with textile sales, and my main tool where my personal shears. Since then I've switched industries and sadly haven't picked them up in a while. But I don't care what the price is! As someone who's had, and relied on scissors as my main tool, I want these so bad!!
This whole journey has been crazy! I’m glad to be a follower since episode one and can’t wait to buy a Baliscissor when you are able to release it
Amazing to watch the process. As a LSS Black Belt and former jet aircraft mechanic, I am enthralled.
Am terrible at reading many comments, but stress relieving before final machining is probably your best bet. Everything in your video shows your skills to be solid and you are way above the norm. Keep it up and do not get discouraged. This was a very fun video to watch.
Sweet! Another Baliscissors Ep!!
Thats so sick that the Squid crew got to flip it!!!! I can't wait to purchase these once they are done!!! Amazing work!
Actually amazing that you go so in depth with this. It's like a master class on making a vision a reality! I don't do many fancy things with my balisong trainer, but I can't wait to see how these come out and how fast you can dish them out to ppl
I just want to express my appreciation of you sharing this journey, I have learned soo much, and just generally have more of an interest in CnC work than I did before..
hopefully, as a thank you, i'll buy one of these from you one day.
best of luck!
I'm excited for the final release I'll be on those like hot cakes and I love that you show all your prototyping and how you're solving all the machinical issues good job
As someone (god I hate using that statement) who spent 6 years learning to sharpen from a wise old dude I can appreciate your frustrations when it comes to scissors. There’s a damn good reason “high end” scissors cost a fortune and you sir are showing the world why !
grats on the progress, I know not being able to have a consistent result at the end is frustrating and is blocking your overall progress but getting to this point is amazing. you have what you may consider production quality. def a few times it seemed almost impossible.
watching your progress has been amazing, also props to Lucas' insane flipping ability!
Man it’s amazing to see how far you’ve come! Keep it up!
I absolutely love your videos! Ill be keeping an eye out for them if/when they become available
I had an idea for the logo orientation. If you have the logo right side up when the baliscissors are closed it turns upside down when they are open, but opening them like a balisong also flips them over. If you put the logo upside down on the back, it will be right side up when the baliscissors are open. I hope that explanation makes sense. I can’t wait to see your next video and some day buy my own baliscissors! Keep up the great work!
The journey of design and creation is long and often arduous. I commend you for your efforts and wish you great success.
I've been obsessed with these since I first saw them. Thank you so much for keeping us so well updated. I know I'm gonna try to get one as soon as they're available!
First timer and subbed. Bravo, what a wonderfully transparent look into your process.
So good for young creative, entrepreneur ial types. I hope alot of burgeoning creative, engineering, self starters see this. My daughter is 11 and I'm going to have her watch this.
Great job.
The saying 'You learn more from your failures than your successes' is so true. It's genuinely fascinating to watch your journey and learn so much from your failures. Thank you for sharing 🙂
I am SO happy I found this channel. I’ve never seen someone make a tool other than a knife in a balisong form factor like this. Several years ago I got into balisong flipping, but as I seldom find myself carrying knives in my day to day life and my baliyo pen broke within a month of using it, so I slipped out of the hobby. A while back I began getting into woodworking though, and when I was trying to find a good way to store and carry my chisels without dulling them while also not using sheathes I’m bound to lose immediately, I came up with the idea of taking an old 1/2in chisel of mine and trying to turn it into a balisong style tool. I still haven’t done much with the idea, but finding this channel has given me a boost of inspiration for it!
Keep up the great work, and I’m excited to see the future of your product!
Dude WHAT?!?!?! A balisizers??? OMFG THAT'S AWESOME! You are the wizard and this is truly amazed me, and i don't get amazed really easily! I want this so bad
Nice! I love your videos!
Congratulations on being the first comment
This is so amazing! Every time the blades turned out bent I gasped with disappointment :D
Can't wait to be able to buy the baliscissors but they will probably be too expensive for me. Guess I'll have to wait and see
It’s finally happening! 🎉🎉🎉 I’ve been here since episode 1 ❤ Can’t wait to get my hands on some 🔪🦋!!
same!
I love seeing the story of the process along the way
your way of problem solving and the tools you use are fascinating
This is probably one of, if not my favorite series of videos I have ever come across on TH-cam. I was recommended part 28 on my page, as soon as it started and I got a taste for what I was seeing, I IMMEDIATELY paused the video and started the parts at part one. Then subbed and binged the entire playlist. I absolutely cannot wait to see the finished product and I have mad respect for the process! Keep it up man, when they come out, you can count me in for buying a pair or two asap! Love the videos, I won't be missing a single one!
Love how the idea gives you the full flipping potential without violating the switchblade acts of various states. I've had trainers (with the holes in the blade and all) confiscated from customs before.
Will you have an Etsy or some other storefront? I rather not request them through email or social media.
I'm still loving watching this project. Have you tried grinding the bevels on the surface grinder with coolant? Might keep temps down.
I haven't really been into balisongs since I was a teenager, but the scissors are pretty cool. This video is the coolest part for me. I really enjoyed watching you work through some of these problems.
This is genius. I am an artist and I use scissors all the time and I love balisongs. I tend to need scissors a lot at work or anywhere else I need them so this would be a nice concealed way to carry them and a stylish way to do so. Keep up the great work man. We need smart thinkers like you
this is so awesome! glad you are nearing the finish line. love watching the vids I will have to pick up a baliscissors when they are sold. Do you have any idea what ballpark the price would be in?
Love the videos man. I just wanted to say that I'm working with a relatively small machine shop based in Amsterdam NY specializing in small volume, custom work. We have the capability to machine, anodize and laser etch your handles, as well as make your custom washers and pins (unless they're rotary ground, we don't have that capability yet).
If you're interested, send me a PM and I can connect you with the people in charge
Hello (almost) neighbor! Greetings from Halfmoon
My wallet is waiting patiently for the release
Same.
I just found your product through this video, I was so interested that I went back and watched a couple of the other episodes of baliscisors. I think that this idea is amazing and it look amazing too, I can’t wait to buy one.
this is so cool, my family owns a machine shop that does stuff like this and its super interesting to watch other people do this kind of stuff with almost completely similar machines and techniques.
6:10 could you tilt the platform so the blade is diagonal to the belt? would use the whole surface of the belt, but i'm not sure it's possible
he could make a block and secure it to the platform to sand diagonally. 3d print it or just cut one out of wood, that'd be easier, cheaper, faster?
This is amazing! I assumed that a balisong combined with something else would be heavy and uncomfortable, but you managed to make it compact and totally flippable! do you know what the final price will be, approximately?
This video has made me why Im sometimes seemingly waiting forever when I saw a functioning finished product like months ago
I’ve never seen a video this in depth about a project I can’t wait to order one
See your videos pop up every now and again on my feed and I’m excited for whenever you do start selling these. Such a neat concept that I can actually see myself using practically outside of just flipping it. Super cool to see your process of making them too
love TH-cam randomly showing me this. I WANT a set. following you so that I can keep up to when they are ready and watch the process
Best Flippin’ scissors ever! Finally a pair you can run with.
Thanks for making this video...not sure how it ended up on my feed, but I watched the whole process.
That was awesome and I hope you get it completed.
I love it so much its literally a trainer but also has a function as scissors
As a welder turned into a machinist ive learned that you can push heat stress out to a controlled point in the steel. More linear cuts result in more heat but your also pushing the stress in the steel out to the end of the cut. Another suggestion would be to have relief tabs that will take alot of the stress out at the halfway mark
Dude shows the whole process of making a product its so dope
You’ve definitely got my interest can’t wait for the final product
I'm just stumbling across this just now
I hope that this becomes a mass produced product one day
Great work 👏 👍 👌 💪 🙌 😀
I really like watching you solve all those engineering problems, and not giving up to get what you want from the product. keep up the good work, and sell me some scissors. :)
I will for sure buy one when they are done!
That is by far the coolest set of scissors ever.
I have been watching your videos since you started this series. Your dedication is limitless even after failures.
Simple, useful, well made and cool. What every tool should be.
Who would've thought that making scissors would have such a big learning curve.
;)
I want one of these so bad, practical, and entertaining.
Great tool you’ve made there. What a journey you’ve been on, too. Thank you for sharing, we know you’ll nail this warping issue
I remember watching one of the first few videos you ever made a few years ago and the difference is actually insane. that looks like a something i could buy from a high quality small company and the other one looked like a concept that would never actually happen. very impressive.
I really want one. Love the dedication to your craft and want to support the project.
This was a random recommended video. I love your level of learning. Make it your self try to supply and improve.
*Tip, I can help.* The milling cutting tools can be hardened further by wrapping a bunch of them in aluminium foil and then (stage 1) slowly cooling them with a little liquid nitrogen then (stage 2) 30 minutes later adding more liquid nitrogen ... overnight (always with Aluminium foil). The tools will become super hard. Then you can take it a step further (stage 3) ... do the same except use lots of liquid nitrogen as in step 2 except place the container into a vacuum chamber for at least 30 min. I assume that you warm them up slowly. The tools will be harder and last longer, they will also be more brittle. The process includes some kind of Aluminium nitride surface coating and lattice hardening. You can also add as a first stage (stage 0) very lightly using the tools for a few seconds first to expose the metal surface a little. The types of milling/cutting tools you should use should obviously be HSS or Titanium coated items (kind of a yellow color).
