The pad has diamond dust on it and comes with the sharpener. The grit is between the medium and fine grit of the DMT fold up sharpeners. It will not help much for a ripped up edge (BTDT).
The edge will get worse when the carbides are used frequently because the resulting roughness prevents a fluent motion.
I agree on the subject of the medium grit fold up sharpener. Itīs my favorite for field use too.
