I recently bought a very well used Busse Boss Street in .22 inch thickness. I found it to be too heavy handled and thick for my ideal camp/edc/utility blade, so I'd like to modify it. I plan to remove 1mm of material from each side of the blade, then possibly skeletonize the tang to lose some more weight, followed by a satin finish, zero convex grind, and re handle. I plan to use the bevels on each side of the blade as a guide for symmetrical blade stock removal, which would leave the blade around 4mm thick with 90 degree edges for use with ferro rods. Is this a safe plan? Would it be faster to use a palm sander or hand sanding? I plan to use 40 grit sand paper to remove most of the material, and I realize it will be a lot of work. Any advice? Am I correct in assuming I will be voiding the Busse Warranty as well?
In this pic you can see the bevels I'm talking about.
