Featuring a CPM-20CV stainless steel blade with a versatile sheepsfoot shape, this knife delivers exceptional edge retention and corrosion resistance. The blade measures 3.375 inches and is hardened to 59-61 HRC for optimal performance. The handle combines red-blue camouflage carbon fiber with titanium construction, creating a lightweight yet durable frame that weighs just 104 grams. The frame lock mechanism provides secure blade retention, while ceramic ball bearings ensure smooth, reliable deployment. The reversible deep-carry wire clip accommodates both left and right-handed users with discreet pocket positioning. At 7.875 inches fully extended and 4.50 inches closed, the Penguin Plus balances portability with functional blade length. The 3.5mm blade thickness provides structural integrity without excess weight.
