My draw for the fixed blade (i'm in the same idea than the balisong with the double point and edge)
I find the idea coooool to kill zombis and demon
For the detail, i'm thinking about 115w8 steel or niolox, and probably g10 and micarta for the handle. (red and black, bolster in a color and the other part in the other).
I don't know if i will have the time to make the two project but that is my aim
