A punch knife is a type of multipurpose knife that sailors traditionally use. It typically had a wooden handle and a metal blade that was sharpened on both sides. The blade was often serrated so that it could be used for sawing. The knife could also be used for striking, as the name suggests.
Punch knives are made with various tip styles, each designed for a specific material or type of hole. Some common tip styles include round, oblong, and hexagonal. The right tip style depends on the material being punched and the size and shape of the desired hole.
Punch knives are used in various automotive, manufacturing, and construction industries. They are a staple in any workshop where metal needs to be worked. In the industry, punch knives are mounted on a trigger to punch a hole in the cut materials.
