I voted for #3, but I think it needs the full "FHL" from the 2nd one instead of just FH.
Since your name is Firehouse Leather, having the FH alone feels like it's missing something. Basically, I think the white lettering for "Craig Ferguson...." works better because it helps draw the eye and it just looks cleaner. When I first opened this up, before opening the pictures, my eye was immediately drawn to that thumbnail.
The first and last just have too much going on. They're cool, but I just don't think they do you justice. Plus, it seems obvious when you stop and think about it, but some people might not associate the ax with a fireman's tool immediately. 2 and 3 have a fairly recognizable design and it would be a LOT easier to work into a maker's stamp down the road. The more I think about it though, the lettering minus the ax on the 4th one could be a cool header for a web page. I've been thinking about this stuff a lot lately since I'm in the process of designing my own, and unfortunately you actually used all of the fonts I was considering
