This knife was originally made of steel, later of chromed steel or stainless steel. Blade and handle consist of one piece, or can be combined into one. In the first case, the blade must be sharpened regularly, in the other case, you have replaceable blades that are attached to the handle. The blade can be straight, convex or curved with a razor-sharp edge. The length of the blade varies between 1.5 and 6 cm. The blade cuts on one or both sides and has a rounded or very sharp point.
It is used by surgeons and veterinarians to accurately make fine, deep cuts during surgery.
The scalpel is also used by the painting conservator who scrapes and smooths the putty applied to gaps in the painting.
