Never heard of the six inch ruler method, what is it?
I've always sort of done it, and even went to the trouble of letting in a (little used TBH) couple of endgrain pieces either end of the stone box to use the whole stone. Haven't needed to flat the stone yet in 30 odd years, but I've got a feeling that's more down to the stone than my efforts.I reckon figure 8 sharpening is a lot of boloney,unless you want a slight camber on a plane blade or gouge sharpening, but for chisels it has no value at all for the chisel or the stone, but has become a dogma for some.
