I have been studying the construction techniques of Japanese bladesmiths, I call this stile of a soft steel jacket over a hard steel core "hot dog in a bun" because that's what the preform billet looks like :). This method is common in Norway and Scandinavia also for pukko knives, however I was told by a smith from Norway they use angle iron for the jacket in modern times lol. I tried it for the first time yesterday, and succeeded so, since "this thread is useless without pictures" I thought I'd do one better and make a video. Thought you guys over here in the custom knives section might be interested to see it too.
I managed to capture everything but forging the blade out before the memory ran out, but the major parts are in there, I hope it's clear but if anyone has any questions feel free.

and here's the knife I ended up with, I forged it by hand a bit after the video, then cleaned it up on the grinder.

Good job, Sam, but that is NOT a knife- that is a veining tool 🙂
Everything looks like a blacksmith tool to me now.

Nice work Sam. I like your set up. Very purposeful tools, simple, uncluttered. So did you start with mild steel and weld in a strip of higher carbon steel? I like that Anyang, what did it go for if you don't mind me asking? Did you deal with James on it? How does it compare to an LG? I'm chock full o'questions today!

Dave thanks, a veining tool? I could see that but it'd be a heck of a lot of work to make a veining tool with a soft body and hard bit 😀
Ironstein Thanks. Yes I started with mild steel and welded in a bit of 1084, plain carbon stuff. IIRC I paid 4500$ for mine, and yes I dealt with James and he was a fantastic guy to deal with too and still is. It hits about as hard as the 50 pound LG I've worked on, bit harder then the 2 25's I've worked on and OODLES more control then any LG I've ever worked on. I love it, takes a bit to warm up in the morning (unheated shop) but once it get's warmed up it hits hard and has great control.

Thanks Sam. Looks like a very serviceable hammer.

I am trying to come up with more work for it, it is really meant for triple shift type stuff. If I can build a market around some of these types of knives It'd be nice to run it 2 or 3 days out of the week just doing billet after billet like this then spend the rest of the week grinding and heat treating.

Looking good Sam. You should either cut down that chisel of yours or make a shorter one. A shorter chisel would be more controllable under the hammer and you would be getting a longer stroke so a harder blow.

I thought those self-contained forging hammers were designed to deliver maximum power regardless of stroke length.

you thought wrong Jim... (sorry):stomp:
Probably more consistent throughout the blow than most types of mechanicals but if you put too much under the die there is just no travel of the tup.. no travel it cant build velocity... no velocity no power...
Whatever you are, be a good one.

Nice video, it's really going to help some people out.
I love that hammer. I recently put mine up for sale locally, I hope it doesn't sell. When it gets cookin' the blow is so snappy, it wants to hit plain through the lower die. and like you said, the control...
What weight oil are you running in yours?
5:14 pm
Thanks guys
John YES I will be shortening that tool, I initially was going to use it for sledge striking but I don't have anyone to do that for me.
Jim it still does have some good power but no they don't do that.
Nuge NO! Not the Pink Pounder 😀 I have been running 30 weight non detergent as advised by James Johnson. Still having trouble with the oiler as you can see in the vid with all the smoke, but I just need to take the time and find the "sweet spot" setting to get it not too much but not too little.

ditto on all the comments about hammer and knife. Very sweet.
I hate to be an asshole but I really hate to see young guys smoking. It's a big waste of money and can fuck up your body in so many ways. I smoked when I was your age too but quit in my mid 20s.
I am 64 now and go to a VA doc. First thing they ask is 'did you *ever* smoke'.:bomb:
It's a fucked up world where cigarettes are legal and weed is not.
Best wishes Sam.

Ah right on and it makes sense if it can't accelerate. I wasn't sure how that all worked out.
You guys have to remember I'm pretty powerhammer ignorant (and in general 😉
Bob: You are totally not being an asshole. I've been smoking for 10 years (started when I was 17) and I regret it every single day. The plan is to quit once the weather warms up so I'm not just sitting around thinking about smoking.

I wasn't going to comment on the weed, but what the heck.
Marijuana is only harmful if smoked and the only reason people do that is because it's the fastest way to consume it. It and it's not active cousins are illegal because it is/was a threat to paper & cotton and now it's a threat to the pharmacoms.
It's another shining example of how our government protects corporate interests.

Another of Sam's threads degrading into illicit content? Noooooooo!

Alright, you talked me out of it. I'm moving (again) to a smaller space so I'm looking to downsize, but for once it's gonna be my own!! Pinkie is one of the littlest footprints I have yet it's up on the chopping block. F that, I just love the manners of the machine and I really like working small.
I moved to 50 weight in the winter and it seemed to help the warm-up a bit. That's my only complaint with the hammer, the "pre heat". Chamfer the rings? Engine block heater? Or warm it up i guess.
As far as a outlet for your knife work, got an etsy page? It's not a substitute for marketing but orders do trickle in even if you don't drive people there and somehow it keeps the paypal juiced for all the dumb crap you buy on the internet. Check this guy out, he seems similar to your gig. His prices are fair for all and he's got almost 100 sales.

Etsy is a neat site. Loads of great pieces on there and they just got a good bit of publicity on one of the morning talk shows :p

That's great Sam, so would that be a Hotdog weld with the works? 😀
