The Runt J4 has a black 154-CM stainless steel California legal blade (black plain). The black anodized handles are milled from T-6061 aircraft aluminum and have cocobolo wood inserts (front and back). Despite the knife's small size it feels very good in the hand (it feels much bigger than it is) and has superb action. It opens like a rocket and locks up solid. The Runt J4 also has a black coated pocket clip.
