Scalpels Handle

Surgical scalpels consist of two parts, a blade and a handle. The handles are often reusable, with the blades being replaceable. In medical applications, each blade is only used once (even if just for a single, small cut).
The handle is also known as a "b.p. Handle", named after charles russell bard and morgan parker, founders of the bard-parker company. Morgan parker patented the revolutionary 2-piece scalpel design in 1915 and bard-parker developed a method of cold sterilization that would not dull the blades, as did the heat-based method that was previously used.[1]
the handle of medical scalpels come in two basic types. The first is a flat handle used in the #3 and #4 handles. The #7 handle is more like a long writing pen, rounded at the front and flat at the back. A #4 handle is larger than a #3. Blades are manufactured with a corresponding fitment size so that they fit on only one size handle. The following table of blades is incomplete and some blades listed may work with handles not specified here.
