I've seen many suggestions for using a dry diamond grit applied to a steel plate for lapping blades and chisels flat. I just can't seem to come up with actual diamond grit in dry powder form. Seems as though it's always a paste or the dry grit is actually just sand paper grit (don't know the technical term).
I've mostly just used sandpaper glued to a peice of granite and lapped things flat this way, but as the sandpaper wears in places it can actually cause the object to be less flat than when I started. Mostly my fault for not spreading the wear out or by not keeping the lapping consistanly in the same area. But my assumption is that the loose diamond powder on a steel plate would help eliminate some of the human error and actually cut much longer.
Where does one find this dry diamond lapping powder?
