Our Ranger Series was created for those challenges that take a little more skill, a little more knowledge and tools that are a little more powerful. The Ranger 51 features a locking, one-hand opening, 4-inch blade that is capable of cutting those more demanding projects down to size. The Ranger 51 also sports a removable ergonomic pocket clip and ergonomic handles that improve the knife’s safety, performance and functionality. It’s safe to say that the Ranger 51 delivers a little more than your typical knife.
