Sadly we will rock a bit as we sharpen. at the very end we tend to rock just a smidgeon, and cause a fine dub. Now we have a bit of an issue. When we rock it [...] The Gritty Details Here is a table of the relative grit sizes of the different standards used. CAMI is the American Standard, and for a long time is was the main standard. The European standard, FEPA, is more precise, and so FEPA graded sandpaper tends to work faster than CAMI. JIS is used for [...] My method of sharpening is to make two extremely flat surfaces that intersect. This intersection is the edge. To make a flat surface flat the first time, I grind it on a flat surface with an abraisve powder. The flat surface I use is a slab of annealed O1 tool steel.
