We now have world war knives that are authentically detailed and fully functional. These knives are made for military collectors and WWII re-enactors. We have German trench knives and daggers that are made by CAS Iberia and Windlass. World War II knives come with a sheath and are very affordable. These trench knives are intended for close quarter fighting whether on the field or in the trenches. The trench knife originated during the first World War.
