The 4-MAX was developed as a collaboration between Cold Steel and custom knifemaker Andrew Demko. It was produced to deliver a folding knife with the maximum strength and performance possible within a 4″ blade limit. Its extra-wide, drop point stonewashed blade is made from S35VN stainless steel. The 4-Maxs tumbled titanium liners and back spacers and 3D CNC machined and bead blasted G10 handle scales provide even greater degrees of strength. Equipped with the Tri-Ad locking mechanism.
