Venev Unicorn Series Dual-Sided Resin-Bonded Diamonds are designed for use in sharpening systems such as Hapstone and TSProf, as well as for freehand sharpening. Diamond sharpening stones deliver excellent performance on knives made of any steel.

The Unicorn Series represents Venev’s premium-tier dual-sided stones, featuring 3 mm diamond-bearing layers bonded to a CNC-milled aircraft-grade aluminum alloy plate. The diamond-bearing layers contain evenly distributed diamond grains within a resin bond. The abrasive layer thickness in the Unicorn Series is twice that of the Centaur Series.

Grits F80–F240 utilize a wear-resistant boron-modified phenolic resin composite binder (legacy binder). Grits F400–F1500 use a proprietary non-abrasive phenolic resin composite binder (OSB binder), providing scratch-free sharpening results.

All Venev Diamonds use FEPA-F grit classification.

⚠️ Attention: Due to the increased thickness of 14 mm, Unicorn and Unicorn³ Series stones are not compatible with any stone cases currently offered. The only suitable storage option for the Unicorn Series is the Roll Bag for 6 stones.
