This knife boasts a steel blade that is serrated along half its length, so it will easily cut through thick material and line. (Serrated blades work by providing an increased surface area while also constantly changing the cutting angle; on the down side, serrated blades are harder to sharpen and maintain.) To handle tough knots, the knife also has a lockable marlinspike. The glass-reinforced handle is designed to withstand both saltwater and the myriad of other types of abuse meted out on shore. A good knife at an affordable price. $29.99, westmarine.com
