The Sharpening Equipment category is made up of grinders for saw blades, straight knives and profile knives. Grinders are for high speed steel as well as carbide tipped or diamond tipped tooling. Generally diamond tipped tooling is sharpened by specialized sharpening shops. HSS and carbide are also often sent out to specialized shops for sharpening, however many larger shops, especially shops running moulders tend to do their grinding in house.
