There is Dan Mink in Crystal Beach. He makes different styles but centers his work on filet knives. There was a write up in one of the knife magazines a year or so ago about him. Michael Tison out of Lakeland makes slip joints, and although he not in that general area, there is Jim Elliott out of Okeechobee. Florida Knifemakers Guild lists quite a few makers in the Florida area, I have just listed those of whom I own their knives and am comfortable suggesting them. Jim Elliott's knives I own several, and have been to his shop. He does GREAT work and he also is a hell of a nice guy. He will do different styles, I don't believe he specializes in any one thing, but I might be wrong on that count.
