Ontario currently holds the contract to produce the Fighting Utility knife for the U.S. military. Camillus, however, is the company that designed the knife that is still issued today unchanged. They also have made more F.U. knives than anyone else. Most importantly, though, is the fact that Camillus has better quality control than Ontario, not to mention that if you do have a problem or a question about the knife you can go to the Camillus forum and ask Will or Tom. Camillus has a real "history" with this knife, as they are the only company that has made the F.U. continually since 1943. Kabar has changed hands several times, and ceased production of the F.U. for quite some time. Ontario hasn't made the knife nearly as long, and won the current contract because of a lower bid. Camillus, not content to rest on it's laurels, has also continued to improve upon it's method of heat treating the knife.
