centers the knife in the device to achieve maximum symmetry and thus the best possible result, centers and fixes tapered blades, additional stop for high knives, such as kitchen axes, a slightly convex cutting edge can be formed by moving between the two stops, robust construction: zinc die-cast clamps, glass-reinforced composite stops, perfectly balanced: most of the weight is distributed over the clamps, which enables a particularly well-balanced sharpening process, slides with little friction and therefore very smoothly along the universal support, with Tormek T?4 and Tormek T?8 and older models can be combined
