In Lake County (outside of Umatilla, FL) you can try Ruff's Saddle Shop. Look them up on the web, get a map to their shop in the country, and take their phone # with you in case you have to call. It may take a bit of doing to get there if you're not familiar with Lake County, but it'll be worth the trip. Or it was for me when I was last there 2 years ago. It is a custom saddle shop, but he's got a real thing for knives and one whole wall of his shop is set up as a display for Spyderco, Benchmade, BRKT, Kershaw, ESEE, Buck, and some other brands I don't remember.
There's also Peterson's Gun Shop between Tavares and Eustis in Lake County on Old SR44. His knife selection isn't as big as Ruff's but it's a bit different than a shop like Bass Pro.
