That's made by Cold Steel. It's called the pocket bushman.Who's the maker on the middle one? My preference is the flipper/assisted style, but I like that one a lot.
I picked one of those up at a gunshow in Charlotte, N C, I believe in the 80's. I wanted it do bad but it just cost too much so I passed. Sometime later I met him at the blade show in Atlanta. Eventually ordered one of his custom folders. Eventually gave it to my nephew. I have a couple if his designs but not made by him of course. I have a birthday coming up in a couple months if you want to give that knife a new home.I'm not a collector, but have accumulated a few knives along the way. One is a knife Bob Terzuola made for me about 35 years ago.
