Easiest Knifemaking Project Ever - Making a Shuriken (Japanese Throwing Dart) from Rebar
ฝัง
- เผยแพร่เมื่อ 14 ก.ค. 2024
- Okay, strictly speaking it's not a knife. But it's sharp and it's made of steel, so it's pretty darn close! In this video knife maker Walter Sorrells shows a ridiculously simple project -- how to make a bo-shuriken, or Japanese throwing dart -- from a piece of rebar. Three different methods are shown, including one which requires no power tools at all. In a second video, Walter will show the hand forging of a more sophisticated shuriken.

I would recommend one final step: Spray paint neon orange to prevent losing them
Neon pink needles neon pink needles
Yessssss!
I did the same but I managed to fit my piece of steel rod into a electric drill. then I spinned the rod against the file.
Does it damage the file?
@@henrydando it wears the file down eventually. But it still works
More like making a prison shank from prison bar 😂😂😂
Another easy way to do this; put rebar in chuck of a drill, put drill in vice, use drill as sort of a make shift lathe and use a file or axle grinder to make the point! How I made some tent pegs a while back.
Really smart... I may do this.
I should that too and I got enough zip ties for the drill's button.
Can he make these?
Sure-he-can!
Good one Walter!
This pun disgusts me. Have a like
Disgusted by a pun...?
Wow, there's not a lot going on in your world is there, Brian. There's not a lot of coherent grammar either, is there. "Have a like" (?)
Perhaps there's a lot more important events going on that deserve your disgust than my appalling little pun.
Cheers,
Bill
people who correct others grammar disgust me. You must not have a lot going on in your life where you feel the need to be a grammar douchebag who worries about petty things such as internet grammar. get a life and learn how to take a joke douche. he was obviously being sarcastic and making a joke. but nice project Walter love the videos and how you show the average joe multiple ways to finish a project.
Well, Brucy Baby you're just easily disgusted. Not my concern.
HANL
The fact that he is disgusted disgusts me
One of 'em fell by point onto my foot, never have I even been so glad that I wore my feet protection
Walter, great video! I really like the message that it's more about creativity and making the tools you have work, than getting all the gear. I have some excess rebar laying around, I'll have to try this!
God bless you Walter for all the time you take to teach us different ways of making a knife with our simple tools
Safety glasses? I only use my safety squints
Anders Assarsson lmao
Shit I'm Asian so I got them bad boy squints 24/7
Congrats on 200k subscribers! love all of your work/videos.
"more or less pointy" - some serious technical jargon there. Excellent! :)
I just found and subscribed to your channel and 2 minutes later you post a new video, perfect!
11:20 ... "AHHHHHH, MY EYE!!" LOL
Another great video. You are a true pro Walter keep the vids coming!
hello walter!!! amazing video! cant wait to see part 2!
Cool tips, I'll be making these for sure, I'll keep ya posted!!!
Great project Walter! You rock!
I love your videos after I see this I've made my own! ;)
Another easy knife making project is making a kiridashi out of a flat wood drill bit. It's surprisingly easy to do, and most importantly it's a lot of fun. I don't have a forge or a way to temper steel yet, so I made one without using power tools to keep the steel as hard as possible, and it came out pretty well - the edge isn't too "volatile" and it's comfortable in the hand.
I made a couple. I wouldn't have thought of using rebar had I not seen this. I have no power tools whatsoever and it took me a long time. I made a target at the bottom of my garden and ended up missing it and losing them both in the undergrowth. I was getting good at throwing them too. Fun little project, thank you.
You posted this video on my birthday. That's awesome! Love your videos.
Thank you for all your vids I finally started making knives I only have an angle grinder and file though
Spray paint these things a neon color makes them easier to find, keeps them from rusting too.
Good job 👌 thanks for making it look easy
Great video. You're channel has kept me entertained and inspired for a while. Thanks for the hard work.

+Snowy 101 HAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAH that's so funny!! XDDDDDDDDDDDDDDD You are the most cancerous person on the internet, and this os not funny at all.
"Now imagine that in your eye" Oh jesus god no!. Awesome vids Walter, Keep em coming. :-)
Making a deterrent for drivers on my lawn, that brought me here. Same basic principle, spikes to pierce tender rubber. It'll be wonderful. Nice video.
this video was pretty cool thank you.
I'd love to see one making a knife from leaf springs. Thanks for the quality contents
realy good idea going to home depot to get some rebar and make some of these for the zombie apocalypse!!!
lawn daaaaarts
assault lawn darts!!!
"Military grade assault style" lawn darts
Spencer Stollery Oh shit, almost forgot my CNN training there. Thanks for the correction!
Adam Bodford paleti
cool and informative video as usual
Cool video, Walter!
Awesome!!!!!!!!
I made one 6 inches long, sharpened on both ends and the metal in the middle cleaned and spray painted. It looks great and the pattern along the length is good for gripping and cool appearance.
Great video. One thing I didn't hear mentioned was fire hazards of grinding ferrous metals on a sander used for wood. You MUST clean ALL wood dust/ chips out if the sander and dust collector port before you grind metal, the sparks can ignite the dust causing a fire or dust explosion. Always keep a fire extinguisher handy. Stay safe.
When I first started making knives with a hand held belt sander in a vice I forgot to take the dust collector off and it was full of saw dust. Lucky day I noticed the smoke followed by the flame and didn’t burn my shed down!
I like how you show different ways to achieve the same result. Request: could you do the same thing showing some different ways one could make a steel striker for flint/steel primitive fire making?
Dem ninja skills though. Love your vids.
this is something really cool!
i like the center as a guide for balance and narrow it down from the center point of each end.
but I used wood but balance was good enough to throw
awesome, thank you
Awesome videos.
In making them, I welded the tip with a hard-surfacing welding rod before grinding, so that the point will last longer & has better penetration.
I used to be a land surveyor and we used rebar for property markers and would grind them like that so that they could be driven in easier and straighter.
I was told that dragging the file on the backstroke helps clear it of the tiny chips of metal you just filed off, thus making the next stroke more efficient.
made some of these out of some 1/4 in 7018 welding rod that had gone bad, was able to harden them we used them like darts when thing where slow around the shop . only difference was we sharpen both ends.
nice beard man nice video
What I do is chuck up the rebar into a cordless drill then just grind it up against a belt sander so as the drill rotates it grinds away perfectly.
What's it like being a dead meme?
You've done this?
oh shit wadup!
pencil sharpener ?
basically yeah
Gratuitous slo mo!
this was a good vid
Thanks so much for your efforts on these videos and passing along your experience.
My question, when you make the better quality Shuriken, why not upset the point to enlarge the area behind the point and taper the body? Seems this method would offer better balance.
Advice to onlookers: in many countries, as well as some states here in the USA (most notably NY, Calif, and Indiana), shuriken and shaken are illegal to own/carry. Check your local laws. Cheers. Great video as always.
They're just tent stakes ;)
Be sure you have a tent handy, if you use that line on an officer. Just sayin ... ;-)
so are deadly farts
Roving Punster fuck local laws.. it is a God given right to possess means to defend yourself against attackers!!!🔫🔪🎿✒✂📌🔨⛏⚒🔧⚔🔫🔗💉⛓☣☢🔱☠👊💀💣💥💨👢👔 because 👮🐷are not present when shit goes down........
LONE🐺4LIFE!!!!
@Dirty Mushroom: Yes, self defense is a no-brainer right everyone is entitled to ... but whether you like it or not, official rules of conduct (i.e., "civil laws") that apply equally to all are the foundation upon which all civilized societies are built, and which give meaning to the word "CIVIL-ization". People who are unable or unwilling to abide by the laws of the society they live in eventually tend to wind up in jail, and ignorance of the law is NOT a viable defense. If you don't like the laws of your State, your best course of action is neither remaining ignorance of nor flouting said law(s), but rather to work though appropriate channels to get them changed. It's either that, or your self defense will devolve to wearing soap on a rope.
Walter I'm gong to try this with the 12" steel landscaping nails they are smoother on the sides and then try a salt brine hardening to see if I can improve the wear resistance. There was some indication of a slightly better hardness in a you tube video. Thanks for the push.
wow incredibile, fare la punta ad un tondino, sei bravissimo
i made some shuriken with some steel rods , i notice that if you give the tip a more oval shape rather than rounded, it goes deeper in the target
I'm not a man of people's words, so would you mind showing us some proof?
thanks ☺
Little tip. If you move your file the exact opposite way. You will get a perfectly round surface. Have the handle at the top and move it down through the stroke. As if you are trying to file a dent into it.
Great video.
Question, could a Dremel be also used in making it? Thanks.
I did that, they work great, to trow them you need some space and a lot of practice
put the rebar in a drill and then Hold the angle grinder upside down. it works great. just spin it with the drill while the end is on the angle grinder
A triangular (or square) crossection will help those darts stick better. I find that a round crossection doesn't penetrate as good and tends to not stick even on direct hits.
an even easier way to make these is to put the rebar in a drill and spin it on a belt sander, this would make the point perfectly in the center
Does he still make videos? These are awesome.
Wow cool
After watching your bo-shuriken video, I wondered if the work to fold the tip so that you get a stronger tip, is worth the effort.
Hit one end with dayglo paint to make them easier to find. XD
Hey Mr Sorrells. How about a quick video showing us how to throw them? =)
they can be called, senbon shuriken or bo huriken.
You ever going to do that karambit video? I'm in the middle of making one and keep running into issues, I'm on my third attempt and would love to see how you approach making one.
My intent is to do it in the next month or so. But I'm not making any promises!
i should try making these
Hello, Mr. Walter. So Is it not possible harden rebar? I made 4 darts and I have fun. Thanks for sharing.
I could be wrong ofcourse but I'm pretty sure throwing needles are called Senbon.
The machinist in me wants to make some out of drill rod on the metal lathe, and heat treat them. The lazy knifemaker in me wants to freehand them on the belt grinder in about a minute. Either way, be something fun to play with, and a nice break from making knives and fixing guns.
I literally just made 4 during this video, chucked a chunk of rebar on the drill and to the bench grinder it goes
Heat to non magnetic quench in canola oil at 130°f then temper at 450 for 1-2 hours twice...it will baton through basalt lol ....💁♂️
Yeah I had one made out of an old screw driver come back and poke me in the belly. It lost most of its energy in a quick spin so it was more if a deep scratch than a stab but the fact it managed to come straight back was quite concerning.
"Lost all but one in the leaves." I was just thinking, it'd be a good idea to paint those so they are easier to see! lol
or a magnet :)
If you lost them in the leaves your next video could be "safety boots" or "dressing penetration wounds". LOL
I saw a blacksmithing video today by Rowan Taylor where he used a drill press as a lathe... that would help with this i think.
walter do a forged in fire episode
Good instructional video. I wouldn't ever use THOSE clamps on a welding project except maybe to hold something sort of close by, but not near, the weld. I would, and do, use THOSE clamps for a lot of my woodworking, but never in a welding situation.
A little tip of you use a sander you can use a drill and get a better edge
.....amazing.. --- perhaps 'one' can use the cheap forge to heat-treat these bo shuriken ;)
nice
I made one and I love it
Mr. Sorrels, were you in the Navy? in one of your videos, you showed a list of metallurgy books, and one of them was a NEETS module.
walter i have a question what every day items would make good knives? what steel things are high in carbon? ive heard wrenches are ok for making and holding an edge.
maybe you could grind some weight off the back two thirds of them to make them fly a bit more stable and straighter
Dads gonna not be happy either with you when he’s mowing the lawn if you lose them in your leaves kids...
Dvanácti minutové video jak uříznout a zbrousit armovací tyč, tak to je fakt bomba, co bude příště, něco složitějšího? Co třeba párátko.
Much cheaper than buying punches. I also can't wait to make these for my rock sling, because with rocks and steel balls, I get middling firing range. Shurikens and spikes are the perfect weighed darts for my sling. Btw, the slinging world record can only be achieved by slinging heavy metal darts or those shurikens you made.
You can harden rebar to an extent, you just have to heat it up to an orangish white heat and water quench it, I have gotten a rebar knife up to 52 Rockwell before.
You could put in a hand drill and use it like a lathe
I'm just thinking if the pointy end is much heavier it would fly pointy end first
I now I just need Joerg Sparve to make a slingshot that launch these.
Hi Walter, great video.
I've a question for you.
Do we need to use a protective mask during manual file granding process? Do the metal particles spread in the air around?
Thank you.
If you have something like a fan running, or it's really windy and your shop doors are open, I would wear something. I tend to wear one anyway, but I am a big baby.
I think you should wear a safety helmet, visor, earmuffs and shinguards. preferably all the time!
Big fan of the gratuitous slowmo.
Hey walter, was it just me or was that rebar kicking off a lot of sparklers for mild?
Shuriken didn't need to be high quality steel , they were just a nuisance weapon to distract before a katana or yari attack . I made mine many years ago from a square shank screwdriver .
I scanned through the comments looking to find an answer to my question but found none. Isn't there a way to case harden mild steel to make the point harder?
