WW2 US Army Engineer 4 Blade Tool Folding Knife Maker Ulster

The WW2 US Army Engineer 4 Blade Tool Folding Knife, produced by Ulster, is a multipurpose pocket knife issued to American military engineers during the Second World War. This model features four fold-out implements constructed from steel: a spear-point blade, a can opener, a screwdriver-cap lifter combination tool, and an awl or punch. The knife’s handles are typically composed of textured steel or synthetic material, secured with steel pins. Designed for utility in field conditions, it was used for a range of tasks including cutting, opening cans, performing minor repairs, and punching holes in leather or equipment. Knives of this pattern were part of standard engineer and utility toolkits for US Army personnel, reflecting the emphasis on practicality and robust construction in military gear of the era. The Ulster marking identifies the maker as Ulster Knife Company, one of several contractors producing folding knives for wartime use.
