It all starts with a knife. A knife that deserves respect and requires proper maintenance. Keep it sharp, the magazine articles say. But this can be a difficult and frustrating process. Old crafts are becoming less important, and tool sharpening skills are no exception. Our mission is to ensure this craftsmanship endures. The idea of knife sharpening being performed by the individual to whom the knife belongs is close to our heart. As such, the support we offer our customers includes information about sharpening stones, abrasives and knife maintenance. We provide modern, high-quality sharpeners that give a fast, long-lasting edge, as well as various stones and accessories.
