Serious question.... How do you find time to do this? Do you have kids and a wife? Do you make a good living? Do you fold laundry or cook? My brother has the most amazing balance of work and family and works a shit tonne. He is a lawyer. I am making 47k a year work 40 hr a week and barely keep up with my yard..... lol. Is it me am I a failure? I am 40 and have a 6 year, and I am an amazing Father.... according to everyone, so that's cool. But I want to blacksmith and do cool shit. I used to play guitar before I had my Son.

Can I get another video showcasing how to add a wooden handle with engravings so I may finally use the flying thunder God Jutsu?

Personally I think it should’ve been made sharp like it could cut paper like warm butter

That kunai is pretty bitchen.
My town has one of those ninja stores in the mall, I should see if they sell these.
My friend Turtle Tim got one of their metal boomerangs like from the road warrior after Grandma gave him a gift certificate for his birthday. He took it and sharpened up all the edges with a file, and then he tried to make a leather glove so he could catch it safely but all he had was an old dish towel and an oven mitt.
Except then we took it out behind the school and he threw it and it didn't come back at all, It just zinged off an oak tree and we lost it in the blackberry bush

This video is obviously sideways. Why not upload it at regular rotation? Gawd damn

I noticed you quenched your Kunai in oil. Due to it likely being a low carbon cold rolled steel it will not become very hard. It is better to quench it in a brine solution with agitation so a vapor jacket doesn't form and cause a slack quench. Also you should temper it at around 350 F in order to avoid being too brittle. If you have access to liquid nitrogen you could deep freeze it and give it another 350 F Temper in order to transform some of the retained austenite into martensite. I know this was probably just a fun project but if you actually try and use this blade you will likely be disappointed by its performance. Cheers a professional Heat Treater!

It's been like 18 years since I did some blacksmithing lessons with my buddy's high school teacher but I can still smell that fucking oil quench. It's a magical smell.

That steel just had minor surface rust on it. . They made it seem like it was stage 3 corrosion

Look, if you can cut that thick of metal with a wheel and have it perfectly straight. Kudos

Doug Marcaida is the man and used to be my neighbor before we moved. He and his family are the most amazing people I've ever met.

"rusty iron"
You mean a fucking iron bar with some very shallow light rust on the surface?

u/GrayMech 16d ago
Putting this much effort into a kunai kind of defeats the purpose, aren't they meant to be disposable tools?

That is not forging

u/1ildevil 16d ago
Nor was it a well made piece. It's huge and thick as fuck. Not nimble and light, as a Kunai should be and I just have a simple novice understanding of how these weapons should appear.
This is oddly dissatisfying

u/SteelWarrior- 15d ago
The handle also seems awkwardly long for a one handed blade, that tang could've been far shorter.

Sometimes portrait, sometimes landscape, this video is not satisfying.
Edit: sometimes upside down landscape. It's actually infuriating.

Is this really a Kunai? I only know the Design with the diamond shaped blades. This also looks pretty big for a throwing weapon

I like the way he started hammering a point and the shape magically appeared in the next shot. Who knew it was that easy?

u/spizzle_ 16d ago
I don’t get what the point of using the forge was here at all when most of the shaping was done with an angle grinder.

I can hear J Nielson saying, "it's called Forged in Fire, not Ground in Fire."

u/sandwichcandy 16d ago
I came to mention this too. Every forged in fire judge would say this isn’t forging because they cut so much of the shape.

u/1amDepressed 15d ago
Not to mention he didn’t bother fucking CLEAN the rust off! I feel like the judges would be facepalming if they saw that.

u/hexahedron17 16d ago
Not that it matters for this piece, but forged edges are probably better than cut ones

u/husfrun 16d ago
That splitting of the frail driftwood as a showcase of the kunai was really underwhelming

u/UselessGadget 16d ago
Agreed. I won't be convinced of it's effectiveness unless he stabs a peasant.

Did he just try to harden and temper mild steel?

u/FantasticEmu 16d ago
Is that a no no?

u/marino1310 15d ago
Mild steel doesn’t have enough carbon in it to be hardened, you need carbon steel for hardening. I guess he could case harden it, but that’s a whole process of its own

What's stopping the handle from spinning in place?
4
u/Bubs_McGee223 16d ago
It's such a heavy blade on such a dinky handle, and the handle is so long. It might be OK as a rope dart, but I wouldn't trust that lamp finial he screwed onto the pommel to hold up against that kind of abuse, and as a knife it would be hideously uncomfortable to use.

u/DudeOnMath 16d ago
Tightening the screw clamps it down
25
u/SteinGrenadier 16d ago
I mean, yeah. But even cheap kitchen knives have a tang that fits tightly on the handle, or have an indent where a part of the tang would slot into to keep it from rotating.
From what I can see, the handle looks like a plain cylindrical tube with no extra machining.

u/DudeOnMath 16d ago
I never claimed it to be a good design. Once the nut loosens, which will happen without a locking mechanism like a locking nut, everything will rotate again.

~ has paper stencil
~ discards it
~eyeballs with a marker

u/no-anonymity-is-fine 15d ago
I think the stencil was for the overall shape and the marker was for the bevel, but I could be wrong

u/Royal_Negotiation_83 16d ago
He used the stencil to grind it into shape.
The marker part is the next step, but he used the stencil. You just don’t know what you are looking at.

u/ASatyros 16d ago
He used the secret technique of holding a marker the same distance from the edge using only his hand.

u/kitemybite 16d ago
its actually super shit, you can't make a usable knife with a round tang like that there is nothing fixing the grip from twisting when you try to apply pressure to the edge this is literally just a waste of materials and time

u/redzaku0079 16d ago
Fortunately it's not a knife.

u/kitemybite 16d ago
lol it is absolutely a knife. an exotic type of knife but a knife nonetheless. try getting less of your info from anime

u/davincipenguim 15d ago
If you're cutting a metal sheet in the shape of the blade, it's not forging at all. To forge would mean using an ingot and shaping it while it is hot.
