The 531 Pardue is ultra-lightweight and very thin, you'll hardly even know it's in your pocket. The black and gray herringbone G-10 handle scales help keep the knife's weight down but keeps it very durable. The AXIS lock, dual thumb studs and reversible pocket clip make the knife usable for right and left handers. The Pardue 531BK has a black finished blade with a plain cutting edge.
Knife is perfect for everyday use, very easy & comfortable to carry. Was disappointed when I first looked at the knife because it's so very thin. I realized it's perfect for when other knifes are too bulky. I've ended up carrying this knife everyday and barley use my other knives. Not the first knife I'd want in the woods but it would be with me anyway since it is so easy to carry in any pocket. I've even carried it in my shirt pocket.
