According to Google a mastercraft 57-9005-2 is a 5 inch bench vice. As a vice is mostly jaws I think you need to elaborate on what you are asking.
The vice jaws are usually provided with textured steel jaw inserts retained in a recess by two machine screws but these could be replaced by inserts designed for special purposes, such as gripping rods or tubes. Jaw inserts could also be made of brass or even lead to prevent damage to the surfaces being gripped.
Mostly when a softer jaw is needed occasionally a pair of temporary fibre overjaws are used.
