This folding knife has a real secret opening and closing mechanism... hence its name! In fact, the knife is opened according to the inclination of the blade, thanks to a ball hidden in the bolster. This unusual mechanism makes this pocket knife a real collector's knife. Stainless, the X5CrMoV15 steel blade offers unparalleled sharpness. The Laguiole Secret pocket knife is 100% made in France, in the workshops of Master Craftsman Cutler Claude Dozorme.
