Hapstone R2 Black is a fully equipped guided knife sharpener with universal angled clamps, whole milled angled clamps, and a Fine-Tuning Adapter already included for maximum versatility across different knife types.

Complete Setup
Everything included from the start. Hapstone R2 Black is a complete system here and now — no need to build the configuration later. It already includes the core upgrades many users add separately.

Versatility
Broader knife coverage. With both universal angled clamps and whole milled angled clamps included, the R2 Black is a strong choice for covering the widest possible range of knife shapes and sharpening tasks.

Precision
Fine angle control built in. The included Fine-Tuning Adapter allows quick and precise micro-adjustments of the sharpening angle. It makes angle control smoother and more accurate during sharpening.

Universal Clamps
Flexible blade positioning. Universal Angled Clamps can be adjusted inward or outward to handle a wide range of blade lengths and geometries.

Whole Milled Clamps
Rigid and confidence-inspiring. Whole Milled Angled Clamps provide a solid one-piece construction for dependable blade holding and excellent control.

One system. Wider sharpening coverage. Hapstone R2 Black is built for users who want a stronger setup from day one. With two clamp styles and fine angle adjustment already included, it covers more sharpening scenarios without requiring immediate add-ons.
More versatility: Universal angled clamps and whole milled angled clamps are included in one package.
Ready now: This is a complete sharpening system here and now, not a base configuration that requires immediate upgrades.
Better control: The Fine-Tuning Adapter helps make small angle changes quickly and precisely.
Broader knife range: A strong option for maximizing compatibility with different blade shapes, sizes, and sharpening tasks.

Two clamp styles in one package.
The R2 Black combines versatile universal clamps with rigid whole milled angled clamps in one kit. This gives you more freedom to choose the best clamping style for different knives without needing immediate add-ons.

Clamp Comparison: Universal vs Whole Milled

Universal Angled Clamps: More flexible in positioning, easy to adapt for different blade lengths and shapes, excellent for general-purpose sharpening.

Whole Milled Angled Clamps: More rigid one-piece construction, confidence-inspiring blade holding, excellent when maximum structural stiffness is preferred.

Why both matter: Having both clamp types in one system gives you broader practical coverage and more freedom to choose the right clamp style for each knife.

Stone Holder
Compatible with popular formats. Supports 6" sharpening stones in Edge Pro and KME formats, giving you wide abrasive compatibility.

Base
Stable and workshop-ready. The platform base with rubber-coated feet helps keep the sharpener steady on the work surface during use.

Complete kit. Upgrade-ready platform.
Hapstone R2 Black includes the essential R2 platform plus upgraded clamp options and fine angle adjustment, making it a strong all-in-one configuration for users who want maximum flexibility from the beginning.
