Trench hand to hand fighting was a horrid manifestation of WW1. Each side developed a variety of offensive fighting knives, not the least of which was the German Solingen produced knife which became a standard for most German soldiers. New made, this knife with 6” blade and serrated wood handle weighs just over 8 oz.
I bought 2 of these. It comes with a belt scabbard, NOT a boot scabbard as they say it does.
