Böker Pocket Sharpener 09BO375

商品説明

Notorious among experts, loved by practitioners. The classic two-stage X-shaped pocket sharpener is probably the most sold and most used sharpening tool in the world. Embedded in the plastic body is a V-grinder made of two carbide segments and opposite, a fine V-grinder made of ceramic rods. Its unjustifiably bad reputation among experts is due to the tungsten carbide V, which does not grind the blade in the true sense of the word, but pulls steel chips out of the cutting edge in the longitudinal direction. If too much pressure is applied and the work is done too quickly, chatter marks appear on the cutting edge, i.e. an irregular and rough grind. The more repetitions and the weaker the pressure, the finer the result. In the second step, the sharpening can be further improved with the ceramic rods. The sharpener is particularly suitable for carbon steels or softer blades. With some inexpensive softer steels, it is even easier to achieve an edge with this than with a whetstone or rod, which quickly throw up a burr or flip the edge with this quality of material. The tool is therefore justified wherever a useful but not perfect sharpness is to be restored quickly and easily. The low price, the small size and the easy use are essential reasons for the success of this concept. Rubberised grip surfaces and rubberised support feet on both sides ensure safe use.
