Specially designed for modern tool steels with a high carbon content (e.g. O1) and exotic steel alloys produced by premium tool makers. The tests that we performed on this stone series show unbeatable results, especially with HSS. The stone contains mainly extremely abrasion-resistant aluminum oxides made in Germany. It removes material quickly and has a hard bond, so it stays flat for a long time. Before use, soak the stone for at least 15 minutes. Can be permanently stored in water. Made in USA.
