This pancake style pocket knife sheath was designed by Smith & Sons to fit our Mudbug, Cypress, Legacy, and Ox pocket knives, but also comfortably fits a full-sized 2-bladed Trapper pattern. Most similarly sized folding knives will fit. If you are planning on putting a knife other than what is listed above in this sheath, feel free to contact us if you have any questions about fitment. (*Pocket knife NOT included*)
