Each of these Case xx Trapper SS with vintage watch parts has a different configuration making each one a 1 of 1. No 2 can or will be the same only similar. Lots of different watch parts carefully placed surround a repurposed watch dial. Both the blade and backsprings are file worked with different configurations.
This knife design is the 27th design officially approved by case xx not the 27th produced
note: no 2 knives are exacty the same. The knife in the photo is a representation of what you will receive. File work will not always be the same but random for this knife.
