The Gerber Sharkbelly is a light-weight pocket knife for daily use. You open the blade with one hand using your thumb. The elongated cut-out in the blade makes this really easy. The handle is made from FRN. This is glass-reinforced plastic that combines a low weight with high strength. Gerber enhanced the handle with Sharkskin grip. That is also where the name Sharkbelly came from. When opened a backlock ensures that the knife stays in place.
