Hapstone Convex sharpening attachment

thingiverse

This is a Convex Edge Sharpener Attachment designed specifically for the Hapstone M2, Hapstone K1, and compatible with the Hapstone R2, M3, and V8 sharpeners. Simply swap out your rear stone holder, located closest to your hand, with this attachment, and you'll be able to hone your knife to a flawless convex angle. I offer two distinct versions of this attachment. One closely resembles the existing clamp on the Hapstone M2 and K1, while the other features a more rounded design with curved convex notches. The ideal choice for you depends on the type of sharpening stones you use. Available at: https://www.thingiverse.com/leadingedge/designs
