A folding scalpel knife is a precision cutting tool that combines the features of a traditional scalpel with the portability and convenience of a folding knife. It typically has a small, replaceable blade that is extremely sharp, similar to a surgical scalpel. The blade can be folded into the handle when not in use, making it safe to carry and store. These knives are used in a variety of applications, including crafts, model making, medical procedures, and other tasks requiring fine, precise cuts.
