The Muskrat (also referred to as a double-end Trapper) is a favorite among many collectors. Originally designed by those who enjoy the sport of muskrat trapping, this slender knife is ideal for skinning any small fur-bearing animal. The knife shape reflects that of a double-end jack knife, commonly using the same frame as the Medium Stockman (47). With the exception of a few, most of these knives carry two identical clip blades that open on opposite sides of the knife. One thing that makdes this pattern unique is that Case has not assigned a designated pattern number to it. In place of the common pattern number stamp on the knife tang, the word "MUSKRAT" is stamped directly onto the blade.
