This Runt J4 model has a silver anodized aluminum handle and a black coated blade with a plain edge.
The Pro-Tech Runt J4 has a 154-CM stainless steel blade with California legal blade size of 1.9". It's outfitted with silver anodized handles, milled from T-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 includes a TiNi pocket clip.
