Unit Of Measure:

A sharpening stone made of Carborundum (Silicon Carbide) with 9 inches of sharpening surface space and a comfort grip wooden handle (14" long including handle). The silicon carbide sharpening stone can be used to sharpen all types and lengths of knives and scissors.  What really makes this knife sharpener stone unique is the fact that it has a wooden handle.   Most carborundum stones do not have handles which makes using them harder and less safe.

Mechanical insulators consider the Carborundum Stone a "must have" tool since the use of a knife is so predominant in the insulation field. Using a dull knife while cutting insulation is not an option, and nothing makes a knife sharper than a Carborundum stone.


You may have never heard of the word carborundum before, but you probably have come in contact with this material before.  It is most commonly referred to as Silicon Carbide, which is a very durable abrasive.  Silicon Carbide is used in sandpapers, grinding wheels, high-end brake pads, and even bullet proof vests.  

*Our 9-Inch Carborundum Silicon Carbide Sharpening Stone is not only for Mechanical Insulators. Some of our customers who purchase silicon carbide stones include fishermen, various types of construction workers, chefs, butchers, or anyone who uses a sharp knife.

    Finally a stone that works incredible thank you !! Cutting through fiberglass and insulation products dulls the knife quick but I go two days now without re sharpening.. I used to have to sharpen every 4 hours .
