The trapper is a jack knife consisting of two blades of the same size. Those blades are generally a clip and a long spey blade. The Trapper is thought to have been developed around 1920. Quickly favored by fur trappers, hence the name "Trapper." The dual blades made them ideal for skinning, particularly the spey blade with it's blunted tip which allowed for skinning furs without puncturing the hide. The Trapper is a staple among the Case family.
