For many years I used Swann-Morton English made surgeons scalpels and blades for opening up the nose, lips, and eyelids on animal capes.
These used stainless steel handles in various (numbered) sizes, and replaceable blades in a variety of shapes.
They worked extremely well for that purpose, but can be dangerous if not used very carefully, as they are supremely sharp.
In the early 90's I had a custom skinning knife made which had a second 'scalpel like' knife retained inside the handle.
It worked very well and was used to skin and cape scrub bulls, buffalo, and boars.
