Oh, the strop. I like strops; they make a good addition to my two 6" and one 4" DMT, and one surgical black AK stone. I havent tried the one in this kit, though everyone seems to like it. But theres a leather crafting store near me, so I just went in and bought three pieces, glued them to sections of 2×4, then sanded the wood into comfy handles. Bought three grits of compound, loaded the strops; good to go. Maybe $20 at most, for all materials for all three.
