The Tefal K2090514 is a universal knife sharpener from the Fresh Kitchen collection, designed to keep your stainless steel blades in top condition. This compact tool features three distinct sharpening slots to handle different blade needs, starting with a coarse stone for repairing damaged edges and restoring blunt knives. For regular upkeep, a ceramic stone provides medium sharpening, while a fine stone polishes the edge to ensure a smooth, bright finish. Weighing only 190 g, the device is built with a plastic handle and stainless steel components in a grey and red finish. It is a practical choice for home cooks who want a quick way to maintain their cutlery, though it should not be used on serrated knives, ceramic blades, or scissors.
