trench knives encompass a wide variety of issue and improvised weapons used for close hand to hand fighting in the ww1 trenches. this (attached) is a screen dump from
http://www.snyderstreasures.com/page...kle_knives.htm which shows quite a variety including the french nail knives. german grabendolch trench knives were usually a bit more conventional spearpoint blade, short or long giard, wood scales, steel scabbard with leather blet loop, etc. no knucklebows...
another more elaborate french nail version, smith had time to forge a real blade on this one. i've seen them with similar triple rod hilts and the more common rough spearpoint-like nail blade. repro's abound so caveat emptor.
