This little knife/tool hybrid is packing one heck of a material list. To start, the Leatherman Freestyle CX features DLC coating for scratch and corrosion resistance, making it great for those adventures that really put your gear to the test. Next the premium 154CM knife blade holds its edge three-times as long as traditional stainless steel. And finally with its powerful jaws, outside-accessible blade, and removable pocket clip, you can use it like a pocket knife, or a multi-tool. And while those last features aren't really 'materials,' we think you'll agree flexibility and adaptability are pretty much priceless any way you look at it.
