Mods.... if you want to move this somewhere else...feel free.
I agree trench warfare is as ugly as it gets, in the mind of someone like me that has never been to war.
Talking to a friend last, night as he remembered the Battle of the Citadel, any battle qualifies as ugly. Some times the silence between battles is worse. He remembers the K-Bar serving him well.
My Winchester, 1897, 12ga. Trench Shotgun, even ,,,at close to 100years old, with me at 52yrs old, can run four rounds of #6shot before the first hits the ground.
Still the military thought it was better to add a bayonet instead of even more shells.(part of this thinking might have been the quality of shells at the time,,, but that is another story) and most probably carried a bladed last resort weapon too.
As Jim points out,, hand to hand combat weapons were an "As You Like It" tool.
What ever made sense or felt right to the user.
As hso points out,, heavy, long winter coats were the "necessity" that bred the "invention" of the spike blade, knuckle protecting 1917 trench knife.
When I first obtained the U.S. L.F. &C. 1917 the only use I could see was to chip ice for my drinks(done and done).
I like to utilize my finds and smile when I think of some soldier,possibly an ancestor (not in this case, blood test on the blade revealed nothing), using the same tool for the same purpose.
After actually holding one and getting the feel of the 1917, I think it is the only knife I have that might penetrate a melee vest. There are three such vests for sale at a local pawn shop right now and they don't stick around long.
...hso ----I checked the link you supplied when I first researched the Corvo,,, would you plz let me know if you have found anything else.
The only thing I've found on my own is the Chilean Military web site(a small part of the vid has some wild slashing but little else) and a youtube vid of the field type with a longer tip.
Scimitar is close but too long.
Ty for any tips
