    • Desktop vacuum sharpener on the suction cup, which allows the tool not to scalle off and frees the hand+
    • sharpener-caste or pocket, which is put on hand+
    • Roller, which is metal rings built into a plastic or metal case+
    • “Fish” – the subject is made in the form of fish, where the carcass of the fish is a handle to hold the sharpener, and the grinding rings or a stone are mounted in the tail+

    Sharpeners with coarser-grained abrasive are produced in the form of manual, electrical and mechanical devices.

    Mediterranean

    Most often, this option is made of diamond, silicon crumb. It is considered the most versatile coating. The device with a medium-trim abrasive copes with the removal of small irregularities on the cutting edge, while giving the blade sufficient sharpness. Diamond spraying is not able to spoil the aesthetic type of inventory.

    It is suitable for scolding knives with a blade width in a half-meter, not more than. Too wide edge is able to spoil sharpener.
