    Those are really nice, Forge. Do you mind talking a bit about how you assemble/epoxy the handle without damaging the etch on the tang? That's something I've struggled with in the past.

    Damage it ....!!!!! I grind it right off,finish the handle completely. Grind the spine to 600 grit, polish(buff) them dip a Q tip in the acid, rub it on the spine making sure not to get any on the blade, wipe with a paper towel dipped in baking soda water, rinse and apply a light coat of linseed oil and wipe off.

    There is no way that I know off to put a handle on without grinding it afterwards.
    Give it a try.

    I was afraid a q-tip was going to be the solution. Thanks, I'll give it a try.

    Super nice Cal. Do you press the san mai into wavy pattern (so the core actually undulates)? I've seen something similar to this, but is was done by removing material in an alternating pattern, then pressing it flat again. This causes the core to have a wave to it.

    Hope you are doing better.

    I press the billet (hot)with some stretching dies to upset the steel and then re flatten (is there such a word ?)
    The toughest thing about San Mai is to get the centre core in the centre and to start with the right thickness of inner core and outer skins. Depending upon the center core thickness when you are done with the billet will determine how high up the blade the pattern goes. Make the center to thick and it will go right to the top of the blade, make it to thin and you will never hardly see it.
    It takes a bit of trial and error and for sure make some notes.

    I can imagine that's tricky. A process that requires a lot of skill. Grinding a few thou more off one side and you've lost the symmetry. And I am guessing you probably can't see shite until you etch it to reveal where the lines are.

    Really nice. I have some micarta kicking around, makes me want to go put it to use, although I wouldn't come close to anything like those two beauties.
