All Hapstone families

The Hapstone Universal Screwdriver is a compact, durable tool designed for everyday use and full compatibility with all Hapstone sharpening system families — R2, RS, V8, and S4, as well as their accessories and modular upgrades.

Design

Portable 7-in-1 solution

It includes seven precision S2-steel bits with a hardness of 58–62 HRC, covering all hex sizes used across Hapstone devices. The aluminum handle (3030 alloy) features hard anodizing, a magnetic bit lock, a rotating end-cap, and knurled grip for confident handling.

All bits are stored inside the handle, making the screwdriver an ideal portable solution for adjustments at home or in the field.
