SGB™ German Blade Featherweight Folding Knives come with the exact same 440A steel blades as traditional PUMA® knives, but feature a new high strength lightweight frame that cuts weight by more than half.  Knife weights range from less than an ounce to 2.4 ounces! Each blade is individually tested to ensure ideal Rockwell hardness of 55-57 and bears the diamond needle Rockwell proof mark. Black titanium and matte bead blasted finishes are available with fine and serrated edges. Available in four sizes.
