Blunt knives are quickly resharpened with the help of a grinder. But holding long knives, especially those with very thin blades, evenly and at the right angle to the rotating whetstone is usually not so easy. This is where the original Einhell device for long knives creates a solution. 100 - 200 mm long knives can be attached in the holder and thus sharpened optimally and evenly on the grinding wheel of the wet grinder with the help of the device. The device is a suitable accessory specially designed for the Einhell wet grinder TC-WG 200. This means that even long knives such as cooking or filleting knives can be optimally sharpened.
