Maintaining a razor-sharp edge on your knives is essential for safety, efficiency, and confidence on the range or in field tasks. A reliable sharpener should be compact, durable, and easy to use under varied conditions so your blades are ready when you need them most.

ACCUSHARP TRI-STONE SHARPENING SYSTEM delivers a practical, no-nonsense solution for straightedge blades right out of the box. The TriStone design integrates three alumina-oxide stones—coarse, medium, and fine—so you can restore a damaged edge and then hone it to cutting-ready geometry. Shop this product

Key features and why they matter

The Accusharp brand is known for practical sharpening tools, and this model (Various) emphasizes versatility. The three alumina-oxide stones are grit-graded: coarse 120 for rebuilding rolled or nicked edges, medium 180 for shaping, and fine 240 for final honing. That progression lets you address heavy damage and finish with a durable, usable edge without swapping tools.

Stability and safety

The rubber-grip base prevents sliding on any surface, improving safety during aggressive strokes. For fixed workstations, the TriStone base can be mounted to most countertops to lock the unit down during repetitive maintenance.

Consistent angles

Included angle guide assists in maintaining a consistent sharpening angle—critical for repeatable edge geometry and predictable cutting performance. This is especially useful when prepping knives for precise field tasks or maintenance drills.

View product details and pricing — the Accusharp TriStone is competitively priced at $26.99, making it an excellent value for a three-stage system with mounting capability and an anti-slip base.

Practical use and maintenance tips

Start with the coarse 120 grit only when necessary to reprofile or remove damage. Move to the medium 180 grit to establish the bevel, then finish with the fine 240 grit for a smooth, serviceable edge. Use light, controlled passes with the angle guide engaged and let the stone do the work—excess pressure removes more material and shortens blade life.

Care for the sharpener

Keep the alumina-oxide surfaces clean and free of metal filings. The rubber base and mountability extend the unit’s useful life by reducing unwanted movement and stress on the stones.
