This sheath is precision sewn and made of very high grade 8/9 oz. cowhide that has a dark brown finish 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 the final water fitting. Fits blades BL411, BL412, BL483, BL545 and many more. Opening is 1-7/8" wide 7-1/2" long. Made from English Bridle Leather Molds nicely Great finish once done
