Spyderco
The Tri-Angle Sharpmaker was Spyderco’s very first product, and its design and function has only been improved since then. This product was designed to be “fool-proof” easy to use. Your knife angles are already set, there are safety guards in place, and you can always buy replacement parts when you run out. This product is so useful for sharpening blades and tools, House of Knives even uses it in our sharpening service.
