Fits BL450. 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. Opening is 1-3/4" wide and 7-1/4" deep. Made from English Bridle Leather Molds nicely Great finish once done
