I slapped these together in ~20 minutes, and I mainly write this to mention cheap hardware. Quick-set rivets–the rightmost three on the hatchet cover–are a pain. In my experience, if the shaft sticks out of the layers of leather the rivet will not set well or the shaft will bend. They work better in a rigid leather like veg tan. They work better if you own the $100+ rivet setter, too. But for a fairly fool-proof rivet I recommend solid copper, and I think solid brass exists also. The snaps used on the draw knife also suck. Using solid clasps or buckles might be a better option.
