SHARPENER

The sharpener is a tool used to maintain and improve the cutting edge of blades and cutting tools, such as knives, scissors, razors, and tool blades. It is an essential device in many domestic and professional activities, ensuring that the blades remain sharp and efficient, while also reducing the risk of accidents due to dull utensils. This type of sharpener is particularly easy to use and is suitable for quick and frequent sharpening. It works by rubbing the blade against it at a constant angle, restoring the cutting edge without removing too much material from the blade.
