Keep your blades razor-sharp wherever you go with the Marttiini Diamond Sharpener Pen. Designed for portability and performance, this compact tool is ideal for maintaining Marttiini filleting and kitchen knives—even those made of harder stainless chrome steel.

The diamond-coated surface handles tough sharpening tasks with ease and precision. A built-in groove makes this sharpener especially useful for restoring the edge of hooks, gutting tools, and even ice augers. Lightweight and easy to carry, the sharpening rod stores securely inside its case when not in use, while the handy pocket clip ensures it’s always within reach.

Whether you're in the kitchen, by the lake, or out in the field, this sharpener is a must-have for reliable edge maintenance.
