Restore Dull Edges
India stones remove metal faster than fine Arkansas stones, so they are the first step for instruments that have become noticeably dull. Finish on a fine Arkansas stone for a smooth, long-lasting edge.
Versatile Profile
The 125 x 40 mm stone tapers from 10 to 2 mm thickness, giving broad surfaces for knives and chisels and narrow, rounded edges for the concave faces of curettes and sickle scalers.
