Work Sharp Benchstone Knife Sharpener — the angle-guided 3-sided Tri-Brasive system that takes the guesswork out of freehand sharpening. Features 320-grit medium diamond plate, 600-grit fine diamond plate, and a fine ceramic stone for that razor polish finish. The Pivot-Response base lets the abrasive follow the curve of your blade for consistently sharp edges end-to-end. Interchangeable 20°/25° angle guides lock in a repeatable bevel — ideal for pocket knives, outdoor/hunting blades, kitchen cutlery, and tools. No water or oil required. Anti-skid feet keep it stable on your bench. A legit upgrade over cheap pull-through sharpeners and a fraction of the price of powered systems. Retails new for $50-$86 — grab this pre-owned unit and save. Ready to put an edge back on anything dull in your drawer, pack, or tackle box.
