About Finishing

About Sanding Abrasives

Also known as Crystolon stones, these abrade quickly to create a smooth or extra-smooth finish on molds and dies. These stones can be used by hand or in power tools with a compatible holder. Choose the shape that best matches the contour of your work surface. We recommend using a water-soluble or oil-based lubricant with stones that are not oil filled.

Three-Grit Sharpening Stones

Three separate grit surfaces enables multistep sharpening with one stone. First sharpen your blade with a lower grit, then sharpen again with progressively finer (higher) grits until the desired edge is achieved.

Three-Grit Sharpening Stones with Oil Reservoir

Rotate the stone to use three different grit surfaces. The reservoir in the base keeps them clean and oiled. First sharpen your blade with a lower grit, then sharpen again with progressively finer (higher) grits until the desired edge is achieved.

Two-Grit Sharpening Stones

A different grit on each side enables two-step sharpening with one stone. First sharpen your blade with a lower grit, then sharpen again with a finer (higher) grit until the desired edge is achieved.

Aluminum oxide cuts more slowly than silicon carbide for finer control. Also known as India stones.

Silicon carbide cuts quickly with light pressure. Also known as Crystolon stones.
