During WWI the firm of Robbins Dudley filled the “Tommy’s” need for easy to use in close quarters fighting knives. They made at least 10 different models and reproduced the 2 most popular versions. Designed for easy manufacture these knives were all private purchase by individual soldiers. This push dagger was designed for stabbing from behind with a natural movement (great for unskilled knife fighters) with the high carbon steel blade held orientated horizontal to the ground (point is sharp, but edges are not sharpened). Comes with original brown leather holster. Has some light oxidation and pitting, otherwise good condition for its age.
