The old AF survival knife has been superceded by a essentially identical blade. The 'new features' are essentially material ; composite handles replace stacked leather, a cast guard instead of stamped with blade catching extensions and a grey phosphate like finish. The hammer finally boasts a proper lanyard hole, with a glorified shoestring attached. the sheath is a retrofit to the first , with a swinging loop attachment and sheet metal point guard. The sharpening stone is unchanged ( awfull) and is carried in a kydex pocket. If the soft metallurgy is unchanged ( they dulled rapidly once you did manage to get an edge), I imagine personel will continue to buy private substitutes.<br><br>
