The Hapstone Convex Attachment is a must-have tool for creating complex convex edges. A convex edge is characterized by a slight rounding along the blade, tapering off to the finest point of the cutting edge.

Compared to other edge grind types, a convex edge offers superior durability and reduced drag when cutting. It has more metal supporting the cutting edge, providing weight and reinforcement that makes it stronger and more resilient.

This added heft and strength make a convex edge less likely to chip or roll under intense use. Convex edges are commonly found on folding knives and bush craft knives, known for their exceptional performance in demanding cutting tasks.

With the Hapstone Convex Attachment, you can easily create this premium edge using your existing range of stones. The attachment allows for precise shaping and sharpening, enabling you to achieve a very high-quality result with your blades.

Elevate your sharpening game and experience the benefits of a convex edge with the Hapstone Convex Attachment. Unlock the enhanced durability and cutting performance that this edge grind type offers, and take your blades to a new level of excellence.
