The Spyderco Tri-Angle Sharpmaker medium stones (Spyderco part no. 204M1) are replacement abrasive rods for the Tri-Angle Sharpmaker system. Spyderco lists them among its Sharpmaker accessory stones, which exist to replace broken or lost original stones and to expand what the system can do. Medium grit is the aggressive grade in a Sharpmaker set, so these are the stones that restore an edge before the fine stones finish it. If one of your original medium stones has chipped or gone missing, this is the factory part that matches the system.

• The grit is medium, the more aggressive of the two grades that come with the Sharpmaker.
