My vote would be the RAT7. Having owned a BK7, RAT7, and Recon Scout, in my opinion the RAT7 is the most functional. The BK7 second, and the Recon Scout third. For a knife in the 7 inch range, the choil on the RAT7 makes it very handy to choke up on the blade to do finer tasks, the drop point won't chew up batons as readily as the other clip point blades. The full guard on the Recon Scout just gets in the way. If you opt for the RAT7, you will most likely have to do a little filing on the handle slabs to make them feel more comfortable in your hand, and this is where the BK7 is better. Handle ergos on the BK7 are the best, but you would have to spend the extra 45+/- dollars to get micarta, and the RAT7 comes with micarta. Another consideration against the Recon Scout is the rubbery kraton handle. Mine deteriorated under a summer of moderate use, still a solid blade despite some drawbacks. Another consideration for some is the tangs. The RAT7 has a full unskeletonized tang, the BK7 is a full sketeltonized tang, and the Recon Scout is a hidden tang. All the knives are solid choices.
