Spyderco

Double Stuff Medium

Twice the sharpening power in one compact stone. The Spyderco 303MF “Double Stuff” combines medium and fine high-alumina ceramic surfaces, giving you the versatility to restore dull edges and polish them to a razor finish—all in a single pocket-sized package. At 1" x 5", it’s slim enough to slip into a pack or pocket, yet tough enough to handle knives, tools, and serrations in the field or at home. No oil, no water—just clean, consistent performance anywhere you need it. A leather carry pouch is included, making the Double Stuff a self-contained sharpening solution for those who want sharpness on the go.
