Sharpening Plane Irons Chisels
DuoSharp stone with the coarse grit on one side and the extracoarse on the other. I also use this same diamond stone for grinding the cutting edge of all my chisels and plane irons. The most economical way to get started with this system is to buy a Norton combination waterstone that has #1,000 grit on one side and #4,000 grit on the other.
