antique fixed blade knives

Just came accross these knives with the passing of my in-law. The first on is an Everitt fighting knife in great condition, from WWII. The second one is a Marbles (M.S.A. co.) knife. I believe it to be late 1800's or early 1900's. What leads me to believe this is on the 3rd line on the blade it reads "MICH--U.S.A." the dash is the key! Also it doesn't have the adjustable nut on the end of the pommel, like all the others I've seen. The third is a Krag bayonet marked U. S. on one side and 1897 on the other. Help me with the descriptions or if you have any comments. Thanks!
