Spydercos Sprint Run Caly 3.5 is made with Aogami Super Blue steel. Aogami Super Blue is produced exclusively by Hitachi Metals at their plant in Japan. They use high quality iron-sand found only there to create different grades of white and blue steels. The steel itself isnt blue or white in color; instead the designation refers to the color of paper the raw steel comes wrapped in when delivered to Hitachi. In Japan it's common practice for steels to be named and referred to based on the color of the packaging the raw steel is delivered in. Super Blue is the highest grade of blue steel and contains up to 1.5% carbon for wear resistance and chrome to elevate hardness and improve edge holding and corrosion resistance. Caly 3.5 folders have converted legions of knife buyers to the benefits of at-ground, thick leaf-shaped blades and this is Spydercos first folder offering with Super Blue blade steel. The blade is 3.5 inches long, thinly ground and plain edged to pass easily through material. The folders profile is founded on the premise that a comfortable and usable pocket knife feels like a natural extension of your hand. Better ergonomics translated into better control. We accomplish this by adding a substantial finger choil that creates a spot for the index finger to naturally settle while positioning the thumb directly above the index nger on the blades spine. The spine has slip-resistant jimping eliminating the hand slipping forward or backward while gripping the knife. The gray G-10 handle features a mid-positioned back-lock with a low profile wire clip to hold the folder deeply in a pocket facing tip-up. Please Note: Due to the nature of the steel, the knives come packaged in special rust-inhibiting paper. Advise if you would like us to open and inspect the knife.
