Brand new, direct from SOG Knives.

Blade: With a full flat grind and subtle clip point profile the slim, 2mm thick blade delivers exceptional cutting ability. Thumb stud or XR Lock deployment is fast and smooth thanks to a ball bearing pivot. Jimping on the spine offers added traction for a secure grip. Matte gray cryo treated CPM-154 stainless steel offers balanced performance and easy maintenance in the field.

Handle: Skeletonized nested steel liners support dimple textured glass reinforced nylon (GRN) scales for a lightweight, weather resistant handle that offers traction and comfort in extended use with a clean look from the hidden screw construction. A set screw inside the handle allows you to switch the pocket clip position or remove and replace the back spacer with the included lanyard loop for clipless carry. The ambidextrous XR Lock is smooth, simple, and solid for safe use. 

Carries via a reversible stainless steel deep carry clip.

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.

XR Lock: An ambidextrous bar style lock, the XR Lock has been tested to withstand up to 1,500 pounds of force for rock solid reliability and secure use with easy, ambidextrous operation.
