The Adamas Series of knives was designed by custom knife maker Shane Sibert to honor the courage and commitment exhibited by our fighting heroes. The AUTO version of Seibert s original design features Benchmade s patented Auto-AXIS pull release design which actuates the blade as well as unlocks it. Benchmade Knife Company is proud to donate a portion of the proceeds from the sale of these knives to the Ranger Assistance Foundation.
