All About Pocket Knives

Hi all, am new here from west central Ohio I have picked up several knives that I can’t find any information about if someone could enlighten me as to the maker of these and roughly how much they are worth I would appreciate it.
First off is the yellow handled knife approximately 8 1/8” long with a 3 1/8” blade length along top of knife is stamped B C Flynn please see pics.
Second knife is a fixed blade also overall length is 10” blade length approximately 4 3/4” Damascus blade no stamping on blade anywhere there is a JJ stamped or carved into end of horn handle?? Jj knife jjknife 2 Jj knife 3

My guess on the deer horn knife would be someone purchased a pre-made damascus blade (many are imported) and vary in quality and assembled a knife.

The second knife appears to have been made by a good custom maker although I could not locate information about the maker.
