CK Tools Sharpening Stone - Double Sided Medium / Fine - 200 x 50mm

The frequency depends on tool usage. For frequently used tools like chisels or shears, sharpening might be needed weekly or bi-weekly. For less used items, sharpen only when you notice a loss of cutting ability.

The medium grit is coarser and used for initial sharpening, repairing minor chips, or reshaping a dull edge. The fine grit is smoother and used for honing, refining the edge, and achieving a sharp, polished finish.

No, this silicon carbide stone is designed for water sharpening. Using oil can clog the pores and reduce its effectiveness.

A sharp tool will cut easily with minimal pressure. For blades, you can test sharpness by carefully attempting to shave a piece of paper or fingernail. A properly sharpened edge should feel smooth, not 'draggy'.

While it can sharpen basic utility knives, it's not ideal for complex kitchen knives or those requiring very specific angles. For specialized knives, dedicated knife sharpening systems are recommended.

With proper care and occasional flattening, the stone can last for many years of regular use. Eventually, the grit will wear down, or the stone may become too thin to use effectively.

Ensure the stone is adequately wet. If it's dry, it will not perform correctly. Also, check if the stone needs flattening or if the grit has become clogged with metal dust; clean the surface with water and a brush.

Confirm you are using the correct grit for the task (medium for repair, fine for honing). Ensure consistent pressure and a proper sharpening angle. Try alternating between the stone and the tool multiple times.

Keep a supply of water nearby and frequently splash water onto the stone's surface while sharpening to maintain lubrication.
