This is the same Swiss Military Surplus Bayonet seen on the SIG SG 510, aka the Sturmgewehr 57. Used in Swiss military maneuvers over rough alpine terrain, where it more commonly serves as both a utility and survival blade. This Bayonet is pretested, but with plenty of life left for the mission ahead. Made to strict Swiss military specs, and a must-have for your collection. 1957 approx. manufacture date Made by Wenger, manufacturer of Swiss Army knives 9.5" stainless steel double edged blade, .875" thick Ribbed, molded 5" handle Metal tang with spring release 2.875" wide hand guard Leather scabbard
