Yes, Iím quite aware this is a WWI threadÖ but I thought it would be best to add these contemporary WWII shots of the U.S. M1918 Mk. I Trench Knife being worn here, so that this thread is a one stop shop for those interested in these style knives. There are no known (Read: Published) WWI contemporary shots with these knives being worn, except for the post-war (Circa 1919) occupation USMCís shot at the start of this thread. Most (but not all) of these knives are shown being carried by Paratroopers. All credit to the original posters of these photos, from various websites on the WWW.
