Can you do a video on sharpening serrated blades?
I currently dont own any serrated blades 🙂
@@OUTDOORS55do you have a specific loupe rec?
Amazing content and photography, you should compile/author a book utilizing all your photos on the subject of sharpening.
Speaking of books, can you recommend any books on this subject (maybe some new video content on recommended reading).
Your content and presentation format are fantastic, thank you Sir.
You are making the world a better place, one edge at a time. My Sypderco Military's CMP S30V blade is wicked sharp thanks to you. 👍
Could you please recommend a good diamond paste. If you provide an Amazon link I'll order some.
I've had great success using the stones you recommend, now I need a good diamond stropping paste. Its difficult searching through Amazon as many of the pastes are in a spray form, I'd rather use a paste in a syringe.
The epitome of the saying “don’t just tell me, show me”. Best knife channel currently on youtube? Strong chance!
Wow thanks Pete! Your channel was a big inspiration for me when I first started, and still is. Thanks for the continued inspiration and support👊👊
I love watching both of you guys as well as Jared’s channel!
Modern day myth busters lol, I feel as if you may be getting close to breaking the internet with these space age thoughts 🤣 thanks for showing and the time invested it is greatly appreciated 👍
Spider-Man pointing at each other meme 😯👉 love to see it
first time seeing both of your channels. instant sub to both! looking forward to some great content from you guys
Hands down the most detailed information on sharpening on TH-cam. We appreciate your work.
not really, go look how they "sharpen" swords in the medieval days
ABSOLUTELY!
I wear my lighted dental loupes when sharpening. When stropping, I can feel the burr"scratching" the leather. When the scratching stops, the burr is usually gone. I have to watch your videos twice. Once to gawk at the incredible magnification views. Once to actually listen to what you are saying. THANK YOU, Alex!!
Can we see which dental loupe you're using? I'm in the market for one at the moment so I'm curious about people's experience of them.
There can still be a micro burr after the scratching stops. Extremely small burrs that are straight (not favoring one side) can go by undetected with this method. Observe the apex closely (rotating the blade and observing light reflection), constantly feel the apex and get used to the feedback on your thumb pad, as to how a burr versus a burrless apex feels, observantly feel how it cuts through paper, glide the apex across your thumbnail and check for resistance, etc. all good methods, especially when combined, at finding the smallest and peskiest of burrs. And your loupe is a big help.
@@twatmunro Orascoptic XV1. IIRC, it was about $2500 when I bought it about 12-15 years ago. I'm not sure it is still available.
@@oceanwaves83 Initially I use my thumb pad to feel for the burr, then I look at the apex for any light reflections. When I get rid of those I then run the end of my thumb nail gently along the edge; this picks up any straight burrs that are usually removed with gentle stropping. I have just ordered a 60/90 magnifier as used by Alex in this video; I'm hoping I can step things up a level.
@@tyrotrainer765the reflection is super useful to determine if you missed a spot sharpening
Alex, would love to see a “closeup” video of what’s happening to the edge during common mistakes (varying sharpening angles, over angles stropping, over aggressive pressure, failed apex’s, etc).
I know why my freshly sharpened knife gets blunt quickly. Because my wife keeps using it to cut the kids fruit and sandwiches on ceramic plates every morning. 😭
Cuz your balls are in her purse
It is strongly suggested to buy a microscope and a diamond to keep fixing that burr
Grounds for divorce that mate.
Did she also run it through the dishwasher where the steel was made more mild?
I was just about to go to bed... oh well, how bad could be 20 minutes + probably resharpening all my knifes?
A cheap little 50x-1000x digital USB microscope for $25 was such a great tool for helping me understand my sharpening results. It really helped me get a feel for how much pressure to use as well as how burrs actually worked and the differences between diamond stones and whetstones and fine grit vs coarse grit. It taught me so much about how tricky burs can be with their false edges. Your channel and advice is spot on; I have also come to the same conclusion that diamond stones are the way to go rather than whetstones, and I also prefer getting a refined apex on a coarser stone. I too have experimented my way into preferring the method of apexing on a coarse stone, and then alternating edge-leading passes with lighter and lighter pressure. However, one last thing that I do to minimize the burr before the strop is I skip from my 300-grit diamond stone to an 8,000-grit diamond stone and do very light pressure alternating passes as well. I find this helps me maintain the geometry a little better than the strop. However, I am definitely not practiced enough to do any of this freehand like you, so I am doing this with a sharpening system that lets me get incredibly consistent customized angles, but still all of the pressure and movements are by hand.
Diamond stones ARE whetstones, so talking about the differences between them, is like talking about the differences between poodles and dogs.
Some diamond stones have contamination by few coarse crystalls. DMT 600grit that I use unfortunately have I guess around 20 bigger individual "dents" that tend to ruine surface, in fact, making it worse than prevous step 320 grit. I can clearly hear clicks and feel stops when trying that 600 grit. I tought they will split with time but in reality they strong as new even after many attempts. Maybe I will try to eliminate them one by one making 2d map and burn by sun light with magnifying glass or scratch it other way, no idea how. It is definitely nice idea to use nickel/steel diamond stone at low grit and go for resin embedded for finer. So, I fear to buy 1200 or 8000 DMT because of contamination risk. Not big deal really, 220+340 actually already so nice, easy to use.
I kind of feel like on in a class when watching your videos.
I fully understand this particular video. I once had this exact problem until rather recently. Your videos guided me to really recognize the burr and work properly to remove it.
I still haven’t gotten to Hair whittling yet. More practice…
It doesn’t get any better or clearer than this…a strop with the proper compound is your best friend when sharpening! Outrageously good photography..next level! Seeing is believing..Thanks Alex ..awesome video MikeR. 🇨🇦
The best knife channel out there. Why? Simple. Instead of just talking, we get hard data in pictures. There's nothing subjective here.
Hello from Ireland. Just wanted to say thanks for all your efforts and teaching! I had tried a few times in my life to get good at sharpening and sucked at it, but your videos helped me to learn how to get an edge using the crap stones I had and after a while I got some diamond stones and made a strop and it's made a huge difference. It's a life skill I'd always wanted even though I'll only really use it for my family/friends kitchen knifes. It's nice to be able to have a few good steel knifes and not need to bin/live with crap knifes. Thanks again, I'll send whoever is interested your channel's way. Hope you go from strength to strength.
Wow thanks so much! Glad to hear you are getting good results. Thanks again really appreciate it🙏🙏
After stropping, I always drag the edge over a synthetic wine cork (that's synthetic cork, not synthetic wine). Works a treat.
I look for burr and defects on the blades with the reflection of a light. A good apex doesn't reflect anything, dulled knives have spots, burrs and even more bent burrs reflect all the way.
I was so full of myself to think that I can feel any burr with my finger or see it with naked eye by turning the knife a bit and catching the reflection of light from the edge. But I took a knife that had no burr (I was absolutely certain) and looked at it through jewelers loupe and surprise-surprise super small burr was still there!
Few more alternating passes on extra fine DMT with pressure less than the knife weight and then 1 micron diamond strop and I got my first ever hair whittling edge! First time after 2 years being into knife sharpening. Cant believe that what I was missing is simply using as little pressure as possible at the end. And I WAS reducing pressure, I just didnt realize how little pressure I actually needed.
Big thanks for your contributions to the knife community. Your videos are the best.
I’ve been a frustrated knife sharpener for ages. I think you may have just enlightened me with what my problem has been all along. 10/10
I like to think I know how to sharpen a piece of steel. But this, this was a GREAT deep dive on the topic. You really laid out how the process progresses. We'll done.
I've been watching sharpening content for a long time, but this is the first video that explicitly showed burr removal. Also discussing the relationship between the last stone used and the stopping compound chosen is very helpful.
The best, knife sharpening and burr removal video on the internet period.
As always fantastic content on this channel.
Alex, this is your best video since "ceramic knives sharpening" masterpiece!
I absolutely love the scientific approach of your videos. Out of all the knife sharpening channels out there, you're the one I always come back to, and the one I'll recommend without hesitation to friends looking for some tips/info. Understanding the process really helps. Your microscope shots are 100% worth it. Thank for the incredible work!
the microscope pictures add a lot of value and really help the information stick, great video :)
The macro photography is absolutely insane. In future could we get a timelapse of paper being cut with the macro to simulate video??
You microscopy is astonishing and very insightful.
This channel is amazing. Actually taking a really good, close look at sharpening and how/why things happen is rare these days. I love this.
Every video you put out helps. Slowly getting my sharpening game up to par. Thank you!
OMFG. I think you just changed my life. I've hand sharpened and carried a pocket knife for about 30 years. I can always get mine very sharp, but I feel like they dull quickly, I always thought, well I sharpen too a fairly shallow angle guess that's to be expected. I tried this and I think I 100% have been just folding my burr. Thank you thank you!
I used to be all about stropping with 6 or 9um diamond emulsion after a sub 1000 grit stone, but I was showed just fast that can polish the bite out of your working edge. I took his advice and have been stropping with no coarser than 1um diamond emulsion after a J400 or 800 stone finish, then a quick 0.5 or 0.25/0.1um strop to finish and it's a world of difference. Next level scary scary sharp instead of just scary sharp. A quality 1um diamond emulsion is MORE than enough to complete deburring after a coarse stone if you properly deburred on that last stone.
That said, I really liked how you only did a few passes with the 6um strop to complete deburring. That's something I could get behind and have had success with, since it's unlikely to polish the tooth out. I think the issue is when people do a lot of passes. A few passes with 6um, then a few with 0.5 or finer and it's insane. Anyway, thx for the video.
That makes me really wonder what one should do to keep it sharp yet achieve mirror polish. I like to finish my knives sometimes to an impressive mirror polished edge. But as you say, often it feels a bit over stropped, perhaps the edge rounds too much and dulls faster.
The fact that clean mirrored edges have no bite is clear but when it also loses its push cut ability faster, its entirely pointless and becomes less useful as a whole.
Bite is just the remains of burrs chipping away, causing a jagged edge. No burrs = no bite, technically. But yeah, many like the micro serrations. Stropping badly can go from reinforcing the apex and making it keener but overdoing can make it full faster from a more obtuse apex, or even worse you've simply dulled it by rounding the apex over.@@magicshon
@@mikafoxx2717 Ive found that over stropping is an issue only when you use bad technique or your strop is too soft. The point of stropping is not only deburring but also make the apex as small as possible so a good angle good polishing compound with no contamination of large grit and a relatively hard and flat strop is key for maximum sharpness.
I absolutely love your vids. They improved my sharpening skills so much and i recognized the mistakes i was making,such as apex stability and burr removal,as you just shown. Thanks and keep up the good work .
I was just typing to comment on how these are your best photos ever on edges, burrs etc ( while still listening to you final words) and heard you mention how long it took, effort you put in. Clearly that effort showed today in what I think is one of your best videos on sharpening. I honestly don't think you could do any better at explaining and visualising. Amazing. thanks so much
Master class in knife sharpening, making my decision easier to buy a stone and begin my knife sharpening journey. Thank you for all the work you do to spread knowledge, greatly appreciated!
Amazing video with great insights into the intricacies of burrs. With your work as a resource, beginners have no excuse to complain.
Such a great communicator. I wish other knife sharpening channels would do as well as you do. Love the lessons!
This is so helpful. As many times as I've watched your older videos, you describe it even further. This is great thank you.
It's great to see a technical explanation that I learnt intuitively over many years of sharpening chisels. That reducing pressure came naturally and is really effective..
Simply masterful. This stands so far above similar channels with its rigourous scientific approach, intelligence, clarity of explanation and quality of presentation. So many other channels suffer from long-winded, unclear, over-excited presentations and this one is a breath of fresh air. I come from a scientific and educational background and this is outstanding. Thank you.
Your camera work is FANTASTIC. thank you very much for your content.
So with a properly deburred edge on a kitchen knife, how long should the edge typically stay clean? And what's the best way to 'touch up' the edge? Back to a fine stone then strop?
Keep up the great content!
That’s a real step up in clarity of description and messaging around instruction. well played!!
Thank you for taking the time to put this together!
Would you be able to expand on pressure required during sharpening and stropping?
Maybe having the stones and strops underneath some kitchen scales to show how much downward pressure is being used?
'Light pressure' and 'medium pressure' etc can be very subjective to each person watching, it would be interesting experiment to see how you perceve pressure compared to others
This is such an informative video! Thank you for taking the time to put this together!
This particular video has helped me a lot. Alternating single light passes to gently eventually bend-break the burr - I finally get it! After stropping on leather the blade is oddly (unnaturally?) smooth when I rub my finger from the dull side and past the apex. But then I carefully test the edge in the cutting direction and it's quite sharp! Maybe after months of trying I've finally sharpened a blade properly! !!!
I picked up one of the lighted "card" magnifiers you used in this. Great advice. I was finally able to see exactly what was going on in a trouble spot I'd had on an M390 edge without needing to reprofile the entire edge, and fix it. 60x was the minimum magnification that let me find it. My old 20x loupe was no help.
Thanks for the advice!
I must say I greatly admire the detail and the proof that you present about your word. We can see it happen as you say it.
Outstanding vid! Burr removal has always been problematic for me. Your solution is brilliant.
I really applaud your efforts in photogrammetry. The results are fantastic.
Alex...you give a truly master-class presentation with each video! Well done!!
Thank you for all you do with these sharpening videos!
Since I follow your tips my pocket and kitchen knives are much sharper for much longer. Well, I still struggle with the really small pocketknives with a drop point blade, but I'll get the hang of it eventually. Thank you very much for your hard work and pristine presentation.
Wave at the beach-nicely chosen metaphor. Very grateful for your content. Extremely helpful.
This is the good stuff. The best way to understand and comprehend sharpening, at least for me. Thanks!
nice job!! I sharpened every knife in the fish house for around 10 years, millions of fish processed yearly. If you're short on leather for a strop, cardboard boxes work really well. Stacks of boxes for packing frozen fish, strop them right on the stack. Works really well. Can't say I'd strop everyone's knives but mine sure got it. Huge difference. Never looked with a loop but you can tell by feel if you're even slightly competent. Again, great video!
Got a Sharpal dual grit on your recommendation, it works great! Thanks.
Simply incredible work! Thanks for sharing your knowledge.
Great video man love these ones. Very informative and packed with crucial tips. Great job love the channel. Best on TH-cam.
Thanks for another great video on sharpening and burr removal. I have really been able to finally have sharp knives!
Thank you for all the effort you put into these videos!
This was very helpful. I’ve had a hard time moving past a certain level of sharp where it will pop hair off but not cut paper towel or pop hairs off like I’ve seen some other edges do. I don’t think I’ve been doing proper burr removal and thank you for the better explanation and demonstration of your burr removal process on the stone
This video was incredible with ao much useful information! I've watched you from say one and boy your channel is top in the class!
Thank you for all the details!! Great video!
Awesome information of an existing occurrence.
Bravo Man
That's was an amazing detailed burr video
Thank you so much for your time ☺️
We're gonna have to call you the Burrman giving us quality video and content on this subject.
This is next level. Thank you
Amazing work Alex 👏🏼👏🏼
Thanks from a straight razor user. I understand now why I strop each shaves. The burr is my edge and I just making it straight again!
I'm from the Burr Anti-Defamation League and we demand you remove this video depicting Burrs as less than equal to an Apex. Burrs are edges too.
Lmfao 🤣
that's cold
I identify as a burr

thanks for the video mate, very helpful
Really informative video. Thank you
EXCELLENT explanation Alex... Very thorough... I can occasionally get ahead of myself on burr removal.. Esp on a steels I don't sharpen often.. Always enjoy your work 👍👍🔪
Thanks for your video. I will try it out on my knifes. Kind regards,
A fine presentation on the subject, and articulated in a manner for effective technical comprehension.
It was worth the care and effort and i do appreciate the numerous relevant photos with explanations.
Thank you.
I'm gonna share this video around, this is great stuff.
Awesome explanation. Thank you for you hard work
Masterfully done
Thank you for explaining what we are looking at on the microscopic views.
No, Alex... I'm pretty sure we ALL know that the real reason our knives dull so fast is because of the elves that come at night and use our tools, which is also why they're never put back in their proper places.
GD elves.
Thank you! Very high quality shots and pictures and very well explained! Keep it coming :)
Thanks for the support my friend 🙏🙏
Fantastic info
yep!
Thanks for this information again, I got my chisel to shaving sharp now :) used a DMT 400 stone and a felt lap with the green 3 micron stuff. Also am getting that 6 micron diamond stuff for a strop I'll be making.
Magnification is very important if you want the sharpest knife.
I also like that you address the burr and pressure, sometimes the lightest touch is necessary during burr reduction.
