The 5400 Runt J4 series has a tanto style 154-CM 1 7/8" California legal blade (stonewash finish, plain). The black anodized handles are milled from T-6061 aircraft aluminum and have ivory micarta inserts on the 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.
