What is Crystolon?
As used in whetstones, Crystolon, like India, is a synthetic material as opposed to a naturally occurring one. Crystolon is actually made from silicon carbide. It is typically gray in color and is a very fast-cutting abrasive. Crystolon bench stones are usually, but not always, larger than typical whetstones running as long as 11 inches or more and 2 ½ to 3 inches wide. They are used to sharpen large straight-edge tools like large kitchen knives, plane blades, large chisels, draw knives, wood lathe cutters and spoke shaves.

What are Crystolon Whetstones used for?
Because crystolon stones are a coarse abrasive they are used to repair badly damaged edges like those with serious nicks or heavily worn areas or to bring up an edge to a basic level of sharpness when in a hurry and speed is more important than edge sharpness.

Should I Use Honing Oil with Crystolon Whetstones?
The silicon carbide crystolon stone is also an open pore stone so oil as a lubricant is a necessity. Not using oil on the crystolon stone will plug the pores with swarf-that fine paste of grit and metal particles-and give you in essence a finer grit stone that will not cut near as fast as when it was new or in good shape.

What Crystolon Whetstones used to be used For:
With the advent of newer types of abrasives such as diamond, ceramics and waterstones, crystolon is not seen near as much as it used to be. In years gone by, it was a popular sharpening stone for tools like the aforementioned as well as axes, hoes, grub hoes, mattocks, scythes, grass whips and farm implements that needed to be sharpened by hand yet in a hurry.

My Experience with Crystolon Whetstones:
A crystolon combination stone was one of the first whetstones I purchased and the one I used to bring up an edge on my first hunting knife. I wore that crystolon stone completely out until it was so thin it broke in two pieces. Because I used lubricating oil, those two pieces cut as quickly and cleanly as when I first purchased the whetstone.

Why use Crystolon Whetstones?
When you don't need a fine edge, just a quick one, pick up a crystolon whetstone and follow the whetstone instructions here and you will find that crystolon whetstones fill a need in any shop, toolkit or kitchen and they work well for any kind of knife material from tough but soft stainless steels to high carbon steel knives and those containing chromium or other hardening alloys.
