About this product
The Faithfull Diamond Folding Whetstone is a portable sharpening tool for tradespeople needing reliable blade maintenance on the job. It has dual grit surfaces of 400 and 600, offering coarse to medium sharpening suited to general purpose use on knives, scissors, cutting blades, and materials such as carbon steel, HSS and tungsten carbide tools. The stone is housed in a protective folding case that unfolds to form a handle, allowing controlled sharpening while keeping the diamond surface protected. Its compact size means it can be carried in a pocket or toolbag without damage. It can be used dry or with water as a lubricant, so no oils are required, making it simple to maintain sharp tools wherever needed.
