In this type of knife construction, I use a method that was explained to me by Gunther Lobach from Scorpio Design. There is a layer of black Carbon Fiber against the bolster on each side. This is to increase contrast, and also to make etching easier. The handle is ground after gluing in the blade, so that the transitions are flush. And then you can use tape / nail polish to mask the handle area, right on top of the black CF.

My added trick to pull off the seamlessness is as simple as could be: I mix pure matte black resin dye in my 2 part epoxy. That way, if there is any small seam in the construction, the black in the epoxy will completely fade away against the black of the carbon fiber and be invisible.

@Victor Creazzi i know you talked about S grind. I discovered something funny. I made a vegetable knife that i heat treated with a straight hamon. At 240 grit polish i put it in ferric chloride... and then forgot i did.

45 min to 1 hour later i had that 'oh shit' moment and quickly retrieved it.

It was not destroyed but i noticed that the hardened steel resisted the etch much better. The result is it has now become S ground from flat ground :)
