For daily carry or ultralight outdoor adventuring, the Altair XR Lock folder offers a sleek, modern look with innovative features. Polymer scales and skeletonized liners are lightweight and offer great durability. A gray TiNi-coated drop-point blade made of CPM-154 is capable of cutting through tough materials but can be sharpened easily. The XR Lock is a bar-style lock that has been certified to withstand up to 1,500 pounds of force and offers rock-solid dependability, secure use, and simple, ambidextrous operation. An added feature of the XR Lock is that it can be used as a secondary deployment method when the knife is closed. The lock can be pulled back, allowing the blade to swing freely.

CPM-154: A particle metallurgy (PM) version of Crucible 154CM that benefits from the refinement in the PM process. A great all-around blade steel, CPM-154 has D2 level edge retention, AEB-L level corrosion resistance and comparable toughness to other PM stainless steels with ease of sharpening/finishing.
