Why You Need This Stone: The Platinum #1500 formulation represents a premium upgrade in abrasive density and speed, bridging medium edge setting and fine refinement. Formulated to cut rapidly across complex, high-vanadium powdered steels without loading or glazed resistance, this stone leaves a refined, silky apex that cuts effortlessly while setting up higher-grit mirror polishes.
Buy This Stone If:
- You sharpen advanced powdered metallurgy steels (SG2, ZDP-189, CPM-S90V) or hard tool steels.
- You want a fast, high-density medium-fine stone that resists loading.
- You seek an elevated performance stone from the Ken Schwartz Estate collection.
