This sheath is precision sewn and made of very high grade 8/9 oz. cowhide with a welt in the seam so the blade does not cut the threads. It is soft enough so that most handles will slide in for final water fitting. Fits the blade BL422, BL431, BL465, BL475, BL481 and BL706. Opening is 5-1/2" deep and 1-1/2" wide.
