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 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.
