I don't really collect fixed blades, I only have a few. My son on the other hand, loves them especially when they're military issued. He has a lot of other bayonets on display, but it is too much of a hassle to take apart and photograph right now. So he let me take pictures of some he already had out.
Here are three of mine. The top two are German and the bottom one is supposedly a cut down banana knife
Here are some of his
LF&C 1917 Trench knife
Plumb Bolo 1917
Ontario and Camillus Pilots' knives
