FAQs
What is the primary purpose of the medium grit stones?
The medium grit stones are designed for quickly removing steel to re-shape or sharpen very dull or damaged knife edges.
Can I use water or oil with these stones?
No, these ceramic stones are designed for dry use only. Using liquids can clog the stone and reduce its effectiveness.
Are these stones compatible with other sharpening systems?
These stones are specifically designed for the Spyderco Tri-Angle Sharpening System and may not fit or function correctly with other brands or models.
How do I clean the medium grit stones?
Gently brush off accumulated metal filings with a stiff brush or a clean, dry cloth after each use.
What type of knives can I sharpen with these stones?

When should I use medium grit stones versus fine grit stones?
Use medium grit stones to establish or re-establish an edge on dull or damaged blades. Fine grit stones are then used for refining the edge and making it sharper and smoother.
Troubleshooting
Sharpening is slow or ineffective
Ensure the stones are clean and free of metal debris. Verify you are using them dry and applying consistent pressure. The edge may be too damaged for medium grit alone, consider professional repair or a more aggressive method if available.
Stones do not fit into the sharpening system
Confirm that you have the correct Spyderco Tri-Angle Sharpening Stones for your specific Spyderco system model. Ensure they are oriented correctly in their designated slots.
Ceramic dust accumulating excessively
This is normal during the initial sharpening of dull edges. Gently brush away dust after use. If it persists, ensure you are not applying excessive pressure, which can overload the stone.

Setup, Compatibility & Care
These medium grit ceramic rods are designed exclusively for use with the Spyderco Tri-Angle Sharpening System. Ensure the rods are securely seated in the appropriate slots within the sharpening system's base. For best results and to maintain the integrity of the ceramic, use the stones dry. Avoid using water, oil, or any other lubricants, as this can clog the porous surface of the ceramic and reduce its effectiveness. To clean the stones, gently brush off any accumulated metal filings with a stiff brush or a clean, dry cloth. If the stones become significantly loaded, they may require a more thorough cleaning; consult the main Spyderco Sharpening System manual for advanced cleaning techniques if needed.
