The TR-3 SWAT is extremely popular with Law Enforcement Professionals and Military. Most likely because it has a slender, well designed handle. It has a multi-task 3.5" blade that on this version is all black. The handle is machined from solid bars of T-6 aluminum. This is a very quality knife. This auto knife is a traditional size and shape. It is the perfect size, has a nice grip, and the blade is very solid. The auto button pops the blade right out and it has a solid snap to it. Definitely one of the better knifes around for all your jobs.
