Cold Steel CS28DD: The AD-10 features an ultra wide ground blade that terminates in a sturdy (yet innocuous) drop point. Ground thin at the edge and honed to razor sharpness, the AD-10 delivers unprecedented cutting, shearing and piercing power in a sub 4\" blade but remains remarkably resistant to bending, breaking or chipping. The handle of the AD-10 is likewise strong and user friendly, with heat-treated, full-length aluminum liners, 3D machined G-10 scales and oversized pins and bolts; it fits snugly and securely in the hand due to its precise contouring and integral finger guard. No folder would be complete without a reliable locking mechanism, so we have incorporated Andrews famous Tri-Ad lock. Its been proven over time to be unsurpassed in strength, shock resistance and durability, and offers unrivaled protection for your irreplaceable fingers. To assure lightning quick deployment and convenient carry, we have equipped the AD-10 with an ambidextrous thumb stud and dual pocket clips.
