The U2 folder utilizes Super Gold Powder Steel (SGPS). It is extremely costly and difficult to work with and requires advanced technology in combination with experienced knifemakers. The advantage of this steel lies in its outstanding edge retention: there is simply nothing to compare today. The slim handle consists of strong composite material, which makes the knife light and pleasant to carry. With nail nicks on either side, the knife is completely symmetrical and is as easy to use for right-handers and left-handers. The traditional lockback function offers no unpleasant surprises, but locks the blade in its open position with a distinct reliable click.
