The ProTech Sprint auto knife has been delighting users for several years now. Built with a Cali-Legal sized 1.94″ blade, the push button auto snaps open with serious authority. There are several things about the Sprint series that make the knife absolutely fantastic. First, the 6061 T6 aluminum handle frame is thin. By thin, I mean amazingly thin. It measures just 3/8″ thick which makes it one of the slimmest auto knives you can find on the market. Second, because it is a ProTech, it is built with some serious attention to detail. The seams, edges and finish of this knife is extraordinary. Third, the Sprint is fantastic because it gives you a knife blade you can depend on for serious every day cutting. This will do more than just open your mail and the occasional package. This knife is built tough enough to cut nearly whatever you need to cut.
