The Smith's Pocket Pal Knife Sharpener features pre-set crossed carbides and ceramic stones, which provide the "Perfect Edge" every time. The carbides on the knife sharpener provide quick edge setting, and the specially shaped ceramic stones are designed to give you a razor sharp edge on either standard or serrated edges. A fold out, tapered round, diamond coated rod is designed for sharpening serrations and small gut hooks. The knife sharpener is compact, lightweight, durable, and comes with a lanyard hole.
