W.R. Case & Son opened a subsidiary factory in Nova Scotia, Canada in 1948 for the purpose of producing a knife for the Canadian military. The factory remained in operation until the mid-1950s. The knives were made according to Canadian military specifications using a pattern that predates WWII. The identifying marks are found on the main blades tang. The knife is basically a slab-sided 6353/1905 pattern knife. The tang on the main blade is stamped MS LTD XX. The MS stands for Metal Stampings, the subsidiary name for the Case factory. The XX is the Case XX stamp common to Case knives. These knives are often erroneously sold as WWII rigging knives. While this pattern knife was used in World War II, the Metal Stampings Ltd. were not used during that war as the company did not exist at the time. If the Metal Stampings knives saw combat it is more likely during the Korean War. Closed Length: 5 inches Blades: Sheepfoot 3 ¾ inches - Marlin Spike 4 inches - Punch Blade 1 5/8 inches
