MTech Evolution Knives are compact everyday carry knives that bring affordable quality knives to the wild world of everyday carry. The MTE-FDR012-BK features the Ball Bearing Pivot System (B.P.S). The B.P.S. opening system is a manual opening system that enables smooth, easy blade opening without the use of a spring or torsion bar to "assist" the blade out of the handle. Instead, the B.P.S. system uses a series of ball bearings that surround the pivot point of the knife blade. As the user pulls back on the flipper blade protrusion or pushes outward on the thumb stud, the ball bearings rotate so that the blade glides out of the handle then locks into place with the use of a frame or liner lock. This knife features a 3.75" 8CR13MoV blade with a satin finish. The handle is fitted with grip enhancing G-10 scales for a comfortable and secure grip during use. Includes a tip-down pocket clip for everyday carry.
