I cut leather the same way, but I strop the blade on a cheap-o 1X30 inch belt sander from Harbor Freight ($50 ish). When the leather belt wears out I cut a new one from 2-3 ounce veg-tan, glue it together with contact glue, put some rouge on it and away we go. I get mucho use from a blade and I think it may be sharper than out of the box. If I need to, I can swap out the leather strap for a sanding belt. Thanks for all your videos.
FYI: cutting straight edges with a plastic straight-edge runs the risk of the blade jumping and taking off a finger tip. It can be don't, as is obviously shown, but using a metal straight edge. I used to do paste-up graphic design, prior to desktop publishing. Of all the hand me down triangles I used for cutting, ALL of them had scratched down the length, with a gap where someone's finger was. The trick is to angle the cutting edge just ever so slightly away from the edge, so it doesn't catch and jump up. Also, once you position the edge, back your fingers away from the edge, like a bad habit. If you're a big fan of severed digits, lots of blood and stitches, then never-mind.
