Smith's 4" Diamond Sharpening Stone

The Smith's 4" Diamond Sharpening Stone is a compact, reliable tool built for those who demand a sharp edge in the kitchen, the workshop, or the field. Measuring just 4" overall and weighing only 2.43 ounces, this sharpener is lightweight and portable, yet rugged enough to handle repeated use. It’s designed to deliver professional-grade results in a tool small enough to fit in your pack, tackle box, or toolbox.

One of the standout features of this sharpening stone is its interrupted surface. This unique design reduces build-up during sharpening, keeping the surface clear of debris and allowing the diamond grit to make more consistent contact with your blade. That means faster sharpening with less effort, and it ensures you’re getting a keen edge every time. Whether you’re restoring a dull knife or putting a fine edge on a hook, the surface works efficiently to bring steel back to life.

Built with precision, the diamond abrasives are engineered to cut quickly and maintain their durability over long-term use. Unlike traditional stones that can wear unevenly or require soaking, this diamond sharpener provides immediate, reliable performance with minimal maintenance. Its consistent grit pattern helps remove metal smoothly, leaving you with a clean, razor-sharp edge in less time.

The compact size of this stone makes it incredibly versatile. Outdoorsmen will appreciate its ability to sharpen fishing hooks on the spot, while hunters and campers can rely on it to keep knives in prime condition deep in the field. For everyday users, it’s small enough to keep in a kitchen drawer yet tough enough to tackle routine sharpening tasks without compromise. At just over two ounces, it’s a tool you won’t think twice about packing along when space and weight matter.

Smith’s has a long-standing reputation for building sharpening tools that balance innovation and practicality, and this 4" Diamond Sharpening Stone is no exception. It combines the efficiency of modern abrasives with a design that keeps the process simple, fast, and effective. No matter where you’re working, this sharpener ensures you’ll always have the right tool to maintain the edge that matters most.
