Original, excellent, and extremely scarce WWII U.S. Navy non-magnetic MK5 Deep Sea Divers Knife. Bronze bladed knife is manufacturer marked on the blade FISCHER SPRING, N.Y., also marked with the contract number C-713051. Blade remains in mint unused condition, never sharpened, nor ever cleaned nor polished, not nicked, and measures its full 6 5/8 inches in length. Maple handle remains in very good condition, is not cracked nor chipped, and has most of its original factory varnish remaining intact. Brass scabbard is all intact including its original leather hanger, remains in very good condition, and measures 8 1/2 inches in length. These knives were standard issue with the circa 1929 Navy MK5 Deep Sea Divers gear. They were also standard issue on submarines. I'm sure if you are a collector you already know how rare the bronze bladed (non-magnetic) version of these knives are. About as scarce as hen's teeth. Maybe 1 out of 1000 of these Deep Seas Divers Knives are of the non-magnetic variety. The bronze bladed (non-sparking) version was designed to be used with explosives and mines. Overall a very scarce knife which would be virtually impossible to upgrade in condition. Absolutely 100% guaranteed to be an original. Buyer pays $10 USPS Priority Shipping, overseas will be more.
