There's nothing quite like frothing rapids and the Herculean force of water crashing around boulders to thrill the souls of whitewater rafters. And there's no watersports knife quite like the Gerber River Shorty or its companion, the River Runner. We built these beauties especially for the unique requirements of rafting, paddling and diving. Medium-carbon stainless steel is the core material, polished to within an inch of its life to limit corrosion. The blade is 3 inches of river runnin' versatility, with the serrated sharp side aiming up rather than down.
