That free knife I was talking about, I think is this one. My question is, exactly what parts of the blade should I cut off, and what shape should I make it? Obviously, I've got to cut down the length, but I also want to make it less wide. If I cut from the side with the sharp edge (and grind a new edge onto it) it'll be stronger, but if I cut off from the thicker side, it'll be lighter and I won't have to grind a new edge. I know virtually nothing about knife craft or how any of this would affect feel, utility, safety or any other feature, so any input is appreciated.
