The Opinel Natural Lombardi Sharpening Stone is a 10cm (3.9") natural stone from the quarries of Lombardi, Italy, made to sharpen Opinel folding pocket knives and any small blade. Best for EDC users who want a pocketable sharpener, it's priced at $10.00 — down from $12.00. Buy online at Cutter's Bench and apply coupon BENCH10 for an extra 10% off.
Wet the stone with water (no oil needed), hold your knife at roughly a 20° sharpening angle — the natural Opinel bevel — and draw the blade across the stone with gentle pressure, alternating sides. The uniform balance of quartz and carbonates cuts quickly under light strokes. Rinse and dry the stone after use.
Synthetic whetstones offer multiple grits; this natural Lombardi stone — prized since the 15th century — delivers a fast, fine edge in one grit with minimal pressure and zero setup. At 1.3 oz, it travels where bench stones can't.
$10.00 vs. $12.00 — the cheapest way to keep every Opinel sharp. Coupon BENCH10 takes another 10%; bundle with an Opinel No. 8 to reach $45 for free shipping.

I keep this next to my armchair and touch up my Opinel while watching TV in the evening. A little water, gentle circles, and the blade goes from dull to scary sharp in under a minute. The natural quartz surface is smooth and consistent. At $10 it's an absolute steal.
Sharpens my Opinels beautifully with just water.
Cuts quickly for a natural stone and the 10cm size is easy to handle. It arrived with a small natural vein running through it, which doesn't affect performance but surprised me. Would buy again.
I'm 68 and have sharpened knives on stones my whole life. This Lombardi quartz is honest — a few drops of water, a consistent angle, and patience. My kitchen knives, my Opinel, even my garden shears all benefit. No fancy gadgets needed.
Does a nice job on folding knives, which is what it's sold for. I tried it on my chef's knife and it's just too small to work comfortably. Also needs flattening occasionally like any natural stone. Fine for the intended purpose.
Came neatly packaged and feels like a proper piece of Italian craft. The surface is even and it wears slowly. My No. 8 Opinel is now sharper than the day I bought it.
No instructions included, so beginners should watch a video on water stone technique first. Once you know what you're doing, it puts a very keen edge on small blades with minimal pressure. Good value.
Light enough to take on hiking trips. Touched up my pocket knife at camp and it sliced through rope and sausage like butter. Sealed it in a small zip bag to keep it wet and clean. Very happy.
Maybe natural stones vary, but mine had a noticeable dip in the middle. The tip of the blade catches on the low spot instead of gliding. I can work around it for small folding knives, but it makes consistent sharpening frustrating. Might be fine luck of the draw, but mine disappointed.
I was skeptical that a $10 stone could do much, but it genuinely puts a working edge on every folding knife I own. Needs only water, cleans up easily, and the natural stone looks nice enough to leave out. Highly recommend for Opinel owners.
