    Scrap-mascus... Do you recycle?

    I've heard another smith refer to the same thing as Scrapahagane.

    Just a thought on Japanese burnishing...

    Hardening of the spine might be more effective, but you might also increase the odds of cracking both in the quench and in usage, especially imho as not much in the way of tempering was done with these swords. I could be wrong, but I don't think nihonto were tempered past a very cursory stress-relief in order to keep a very hard cutting edge.

    Just a thought on Japanese burnishing...

    I'm not so sure. Although nihonto were quite hard at the edge, most of the time the back was very soft indeed- from everything I've found an RC 20 or less would be normal in those areas, and even a minor amount of surface hardening would be a good thing for parries. Although most open warfare had stopped in that period, duelling was still quite in vogue.
  4. I was thinking, recently- dangerous, I know- I wonder if one of the reasons for burnishing the sides/backs of Japanese blades was to impart a level of work-hardening to an otherwise soft surface, so that in practice or in dueling those areas might get less scarred if parries were done with those parts of the blade?

    Dad's design

    That's okay. I got careless at home checking out the fittings of a 400 year old katana. Blade went through my slipper, through my foot missing the bone, and tip hit the floor. Tip was fine, foot healed fine after I put pressure for about a half-hour, barely even left a scar, never got stitches. Blade was a Bizen-style with long kissaki. Still have the sword almost 40 years later. Threw out the slippers.

    Cutlers anvil

    Here's a good short showing one of that pattern of anvil in use for sword blades.

    The incredible disappearing steel

    My average steel loss in doing up a steel billet over 300 layers is 40 per cent or even more, and that's using a press and a good gas forge setup. Scale happens. As for compression- that's not happening. You're not going to "compress" anything unless you're starting with really raw bloomery steel.
  8. ...while drawing a soft temper on the back? I'm thinking of making a dotanuki styled blade (slightly wider/thicker katana style) from oil-quench patternwelded alloys (1084/L6 or 15N20) but using this paste on the edge while I draw additional temper on the blade back, so I get a back hardness in the 40's whilst maintaining a cutting edge in the high 50's. Sort of reverse hamon thing using the paste if you follow me.

    To foil or not to foil, that is the question.....

    For most simple steels, foil is a waste, for things like 440C that need a long soak, they are a must. Scale on 440 is basically chromium oxide which eats abrasives like it is an abrasive- which in fact it is.

    Edge geometry

    Short answer- yes, or perhaps yes. Long answer- what kind of knife or you talking about? There is no such thing as an "ideal" edge geometry.

    Wayne Goddard RIP

    I had breakfast with him at the Atlanta show with my wife the year after I got my JS stamp. An incredible mind.

    Reminds me of a Douk-Douk.

    Forge Press Design Help

    I gotta second this. There's no way I would trust the welds, it looks like a lot of them are not penetrating.

    5160 Steel.....For a Real Leaf Spring????

    From my understanding once the fabrication of sword blades became a higher tech industry with more controlled heat treating, military swords tended to run from the low 40's to the low 50's depending on manufacturer.
