The S.T.U.F.F. (Sheepsfoot Tangential Underpin Friction Folder) knife is the first friction folder in the Menovade line of knives that features a little small twist. This model has a 1.75" long CPM 154 chisel ground blade with matte carbon fiber handle and features a titanium pin detent that *clicks* when the knife is fully opened. The function of this detent is to provide some added comfort and security for the use
