I posted a related question in the smith's corner section.
I'm making a hira zukuri tanto (but out of m390). Except for the steel, I'd like to make it as close to a typical kamakura tanto as possible.
The one I'm posting about is the bottom one. The blade measures 8.5 inches, and the tang is 3.5. This picture is somewhat old, I have refined the niku a bit since it was taken, but you wouldnt be able to see it at the angle in this picture anyway. I'm getting ready to finish the blade before sending it to peters, so I'm wondering how much niku would be typical for a knife this size, and what would be the minimum angle behind the edge that an m390 fixed blade of this size could take and remain stable for medium-heavy use (like skinning large game). I want to know how a traditional tanto's profile would compare to the achievable geometries with modern materials.
Does anyone have any recommendations for refinements to make this more like a traditional knife? I am thinking about making the kissaki a little more acute, but I'd like input first.
