I like WW1 trench knives.
I have one of those, an authentic one, it is an incredible weapon from pommel to blade. It is a knife that I would like to carry, but it isn't legal here.
Sometimes when talking to a female about women in the military, I put that into their hands and describe the functions of it's parts, and I ask them if they think that females belong in a workplace where that is a killing tool, in hand to hand combat.
