Designed by world-renowned firearms expert Massad Ayoob and originally introduced in 2001, the Massad Ayoob folding knife featured a distinctive negative angle between its blade and handle. This aligns the blade with the bones of the forearm to ensure a more direct transfer of force during thrusting and cutting motions and shortens the blade's opening arc. This long-awaited Sprint Run expression of Ayoob's design features a blade crafted from CPM-CruWear-a specially formulated air-hardening tool steel renowned for its edge holding and toughness. Its handle features full, skeletonized stainless steel liners, a sturdy back lock mechanism, distinctive gray peel-ply-textured G10 scales, and a black-coated four-position pocket clip that provides a choice of left or right-side tip-up or tip-down carry.
