The Tormek Original Grindstone is designed so that it can be treated with the stone grader to change its quality from fast grinding to fine sharpening. Once you have created the desired shape on your tool, for example a chisel, you can get an even finer edge using the same grindstone, the same machine and the same jig and settings. Besides the convenience of not having to change equipment, you are guaranteed exactly the same edge angle.
Change to fine sharpening: press the fine side of the stone grader towards the stone surface for about 30 seconds. This alters the surface of the Tormek Original Grindstone (220 grit), making it work like a 1000 grit stone.
Activating the grindstone: to go back to the original 220 grit, simply press the coarse side towards the stone for a few seconds until you notice the stone surface changing. To keep the stone fresh and efficient, use the coarse side when needed. Press it firmly with your hands for about 30 seconds. This does not place excessive wear on the grindstone and can be repeated any number of times.

There are several good ways to sharpen chisels and plane irons: water stones, diamond stones, oil stones and sharpening machines such as Tormek. All give sharp edges, but they differ in speed, maintenance and price.
A honing guide makes it easier to keep the same angle every time. The most important thing is to find a method you enjoy and use often. The guide helps you choose.
