this thing is absolutely amazing. The belt itself is well made. Runs smoothly, no "dump" seam. Looks strong (I did not long ago). The composition I received was a bit difficult to apply. Just too crumbly and more of it broke and crumbled into dust/crumbs when it first made it onto the belt. The trick I found was to put just a drop of regular vegetable oil on a sanding block (obviously wax/oil based). This softened the surface just enough for the belt to pick up a bit and guide to the surface. This will put a razor edge on just about anything - assuming you already know how to sharpen that thing first. You really have to get the blade very sharp first and then sharpen it until you say goodbye to that strap and link. This belt is in place of work. I made the edge of the chisel so sharp it went right through a leather work glove. So be careful. Great. Buy one.
