What's the secret? I have a Whall clipper to do the Schnauzers and the
blades are about $20 new so, I figured I could surface grind them. I jigged
them up and took about .010" off top mating surfaces and I thought I did a
good job but they don't cut at all and I can't see why not. The look like
they should! Am I missing something? Are they magic?


The magic is a 15" disk with a 0.5 or 1.5° taper (I can't recall
which). Glue on grit is 60 to 220. 800 rpm. Blade or comb is placed
close to outer edge with abrasive advancing against the point of the
teeth.

This slightly concave surface insures the cutting pair contact at the
teeth points and the heel. Last time I checked, retail for the disk
was $510.

Can someone quickly tell me what the surface radius would be at 15"?
