One word: Lansky.

BTW, bench grinders have probably ruined more blades than anything else The garden variety spins at 3650 RPM, way too fast for grinding carbon steel. I use one to sharpen my lathe chisels which are high speed steel and much harder to burn than ordinary carbon steel. Even that requires a very light touch with a white wheel to avoid burning and destroying the temper of the steel (when the steel turns blue, you've destroyed the temper.)

Besides, sharpening is actually honing. You only grind when you need a new bevel, which you should just about never need on a knife.
