Spyderco Tri-Angle Diamond Sharpening Stones Pair

The Spyderco Tri-Angle Diamond Sharpening Stones are sold as a pair of 7 in triangular rods made for the Model 204 Sharpmaker system. Each steel triangle is coated with a bonding agent and then covered in diamond particles, creating an aggressive abrasive surface for stock removal and edge restoration. This sharpening tool is intended for edge maintenance, so grit, abrasive type, and the shape of the sharpening surface are the most important selection points.

Spyderco specifies these rods for reshaping, re-beveling, and re-profiling cutting edges when the standard ceramic stones are not aggressive enough. The pair installs directly into the Sharpmaker base, allowing heavier corrective work to be performed within the same guided-angle system. The stones are made in Japan.

The Spyderco Tri-Angle Diamond Sharpening Stones Pair fits naturally into a knife-maintenance kit for users who prefer to handle routine edge care themselves. Buyers should consider both the grit and the physical shape of the sharpener so it matches the knives or tools they expect to maintain. This type of sharpener is especially useful as part of a staged system where coarse work, refinement, and final touch-ups are handled separately. Explore more Sharpeners.
