Honing stones are an essential part of tool maintenance. Our chisels and plane blades gradually dull through use. But the very act of sharpening those can damage the honing stones we use, creating gouges in the surface that make the surface of the stone uneven. The more uneven they become, the less effective they are.

Our silicon carbide flattening stone (180 × 58 × 25 mm) provides a quick and easy way to maintain your honing stones, flattening the surface. While doing that, the stone also removes metal filings, which could be clogging up the pores in your honing stone, reducing its effectiveness.

Frequently Asked Questions

What does the flattening stone do?

The flattening stone restores a flat surface to your honing stones, ensuring even contact and consistent sharpening results.

What is this flattening stone made from?

It’s made from silicon carbide, a durable abrasive that quickly removes material for fast and effective flattening.

What size is the flattening stone?

The flattening stone measures 180 × 58 × 25 mm, providing a stable surface that’s easy to control while flattening.

Why does the stone have a slotted pattern?

The slotted, self-cleaning surface allows metal filings and debris (swarf) to escape, preventing clogging and keeping the stone cutting efficiently.

Which stones can I flatten with this?

It’s ideal for flattening water stones such as the Sharpmate 400/1000 and 3000/6000 stones, as well as other similarly sized honing stones.

How do I maintain the flattening stone?

Rinse it after use to remove debris. If resurfacing is needed, use emery cloth on a very flat surface to restore optimal performance.
