This Runt J4 has a black DLC finished 154-CM stainless steel California legal blade with a partially serrated edge. The black anodized handle is milled from T6-6061 aircraft aluminum. 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 TiNi pocket clip.
