I drew something up today that kind of peaked my interest... After some tweaking some forehead slaps, I'm pretty set on this design. As you can see in the pic, I'm still figuring some stuff out:
5/16" or 3/8" thick?
A-2, D-2, or Hi Carbon with a hamon?
Red/black, orange/black G-10, or G-10/carbon fiber laminate?
Got some planning and buying to get on... I hope to put this to steel soon. We'll see how it ends up.
