The Bat Attack is super unique and a ton of fun. The Bat Attack has two black and satin finished 1045 steel blades, both of which are spring assisted! Just give the thumb-stud or spine flipper for either blade a push and the blade opens up automatically the rest of the way! The handle tops are blue coated aluminum and sit on top of a steel frame with liner locks. The knife has a removable black coated steel pocket clip and nylon sheath.
