Overview
Extremely hard to find good examples. This is a WWI trench knife made by Au Lion, a French firm that helped to supplement the supply needed. Cast Brass handle with U.S. 1918 stamped. The blade is double edged, .204" blade stock and 1.022" blade depth, hidden tang construction. Has rust/oxidation on the blade, some dings on the handle, otherwise good condition for its age.
