Raffan's sharpening method

[Tiger]

Richard Raffan who is a woodturner sharpens his blades on a 6 inch bench grinder by just touching the tooth, I can't make out whether he follows the angle of the tooth or just snips a bit of the tooth's end. Does anyone use his (or a similar) method as I'm wondering how well it would work.

their is a kiwi book by philips where they use a 100mm angle grinder to remove the top of the tooth , works well , if you have a steady hand and good eyes . best of luck bob.
