It is not only professional chefs who rely on sharp knives. Through frequent use, even the most expensive chef’s knives, vegetable or meat knives lose their sharpness and need re-sharpening. With the right tool, anyone can sharpen knives easily and quickly themselves. The TWIN sharpening steel is made of highly carbonized and hard chrome-plated steel with a hardness of approximately 62 HRC and is recommended for sharpening all your fine-edge knives. The black plastic handle is comfortable to hold and won’t slip, contributing to its ease of use.
