At least I think I did. What was I thinking?

So uneven top and bottom.
So since it needs a piece of 416 tig welded on anyway and it's going to get a wa handle how to fix it?

Grind it even and have a very skinny tang?

Cut it flush and make the whole tang 416 and even?

What do you think?

Thanks
 
I don't see any problm. Weld on the extension and put the wa handle on. The difference in the top ans bottom machi don't matter.

The hammer marks on the edge area are a concern. I assume you made a hammer for texturing the upper bevel on the blade to leave forge marks. I'm not sure why you hammered the edge area with it, though. Personally, I would not texture suminagashi.
 
OK, I know what you got now. The whole billet goes through a texturing roller to add activity to the cladding. That will grind away toward the edge as you expose the core. Nothing to worry about.
 
I believe most Americans don't like a "machi gap" where the tang enters the handle, so the difference shouldn't be visible if you install it flush.

That looks cool, I'm glad I don't have any money to buy steel from Dictum right now. :eek::)
 
Last weekend I finished cutting up six meters of suminagashi from Dictum into kitchen, Japanese, and utility blade blanks. Mine was not textured, but that is the way I ordered it. I also cut up four meters of damasteel into all sorts of kitchen blades. I couldn't help myself, so I also cut out a yataghan, a wakizashi, and a tanto in damasteel. All these will be my fall and winter grinding projects.

Dictum steel has been really a good buy lately while the dollar has been strong. IIRC, I paid about $60USD a meter for the suminagashi.
Damasteel is insanely priced at around $600 a meter, and if it wasn't for the "why not" factor, it would be far better to buy ten meters of suminagashi for the same price as one meter of damasteel. A gyuto in damasteel has to fetch $500-750 just to make it worthwhile. The same blade in suminagashi can be sold at $200-250 with a higher profit margin.
 
Not only "nope", but he!! nope!
Generally, Damasteel will run $20-25 an inch for shorter pieces. $600-700 a meter for full bars ( best deal). That is based on a standard .125X1.5" bar.
