At last... A sharpening system that is simple - and really works! How many of you have used sharpening systems over the years that you've discarded because you can't seem to get that edge you really want, or simply can't achieve? Or is it that you can't seem to find the correct angle that your blade requires? Finally your problem has been solved with a completely new design for sharpening all sizes of knives - from pocket to fixed blade to kitchen - called Vulkanus. This revolutionary design, by Austrian Harald Stallegger, will guarantee a razor sharp edge after only a few swipes. This patented spring-loaded mechanism allows you to pull the blade through the hardened steel inserts along the blade surface, all the way to the tip. And by the way, Vulkanus tackles another problem. It is designed to sharpen serrated blades too!
