The Hapstone R2 Black is the most advanced edition of the R2 series — a high-performance, fully modular sharpening system for demanding knife enthusiasts. Built on the Hapstone Modular Platform, it combines precision, flexibility, and premium components — all packed into one complete sharpening solution.
What sets the Black Edition apart is its rich configuration. It is the first R2 model to feature four clamps by default — two universal angled clamps and two whole milled angled (fillet) clamps. This combination ensures excellent performance with a wide range of knives — from compact EDC blades to long kitchen knives.
In addition to the rotating clamp module and digital-ready stone holder, the Black Edition includes several exclusive accessories out of the box: a digital angle gauge, a fine-tuning adapter, spring-assisted stoppers, and a ball-end hex screwdriver. It’s the ultimate upgrade for anyone looking to get the most out of the Hapstone R2 platform.
