Two-Stage Suction Cup Roller Sharpener

Behind the somewhat complicated and official German designation lies a simple, yet ingenious grinding device that offers exactly what its name suggests. In the usual angle-guided pull-through devices, there is a carbide V that pulls small chips out of the cutting edge in a longitudinal direction. In the suction cup roller grinder, on the other hand, two diabolos made of mechanical ceramic with an acute angle in two different grit sizes are hidden. By pulling the blade through, these diabolos are set in rotation, thus sharpening the cutting edge in the true and professional sense. The lever suction foot creates an enormous adhesion which holds the roller sharpener immovably on smooth surfaces. For all steel blades with a flat profile such as chef's and butcher's knives.

Warning and safety information:
Cut injuries: The most common danger when using knives is the risk of cuts. Sharp blades can quickly penetrate skin and tissue.
Slipping of the knife: Improper or excessive pressure can cause the knife to slip, resulting in uncontrolled movements that can cause injuries.
Injuries due to falls: Knives should never be left unsecured or near table edges to prevent them from falling and injuring someone.
Blunt knives: Blunt knives pose a greater risk of injury as they require more force and can slip more easily. Knives should therefore be properly sharpened regularly.
Improper use: Using a knife for tasks for which it is not intended (e.g. as a lever tool) can not only damage the blade, but also lead to accidents.
