Why JTECH Diamond Stones?
Consistent sharpening requires more than abrasive material.
Stone hardness, diamond quality, surface consistency, and manufacturing precision all influence the final edge.
JTECH Diamond Stones are engineered to deliver consistent sharpening results and predictable edge quality throughout training and competition.
Each stone uses a dual-sided configuration, allowing two grit surfaces to be integrated into one precision sharpening tool.

Dual-Sided Grit System

Four grit levels provide a progressive sharpening range: Black 140 (Coarse) · Blue 400 (Medium) · Red 600 (Fine) · Yellow 1200 (Extra Fine).
Standard combinations are configured for the most common sharpening requirements, while additional grit combinations can be customized when required.
Two surfaces. One stone. A complete sharpening progression.
