Spyderco's ultra-fine ceramic bench stone is flat, thin and ultra-smooth for professionally finishing and sharpening wide tools like chisels, large blades, wood-working equipment, plane irons, even ski and snowboard edges. Made from Alumina Ceramic, it is manufactured in the United States using a process where a binding agent is combined with Alumina particles that are actually synthetic sapphires. Alumina ceramic stones measure 9 on the Mohs hardness scale (out of 10) and does not require lubricants like oil or water for use. The ultra-fine grit stone tightens and smooths the cutting edge's scratch pattern for an even keener, hair popping edge. The stone is thin and light enough for hand held use, taking the sharpening surface directly to larger items. When table top sharpening, using the stone on top of its suede carrying case for slip free use. To clean the stone, wash it in fresh water and scrub with a powdered abrasive cleaner and a scouring pad.

What I understood was that the stone, as it is ceramic is measured in microns. This stone I saw advertised as 3 micron which converts to 8,000 grit. I have included a link to share with you the conversion table. https://www.gessweincanada.com/category-s/11328.htm **Q: How does this stone compare to Black Arkansas stone ?** A: I suspect it is as fine or finer than a hard Arkansas stone. I love mine. I still use a leather strop for the final honing which is probably overkill based on how fine the spider stone is. **Q: Will this stone work on my Japanese knives at 62 rockwell?** A: I use this for my straight razor **Q: So, I see some say it isn't perfectly flat and they use different methods coarse DMT, etc. to flatten it, so won't that "rough" it up too much?** A: I had the same concern as you so did not use a dmt diamond to grind the ceramic flat. The many tiny hills and valleys on the ceramic surface are very apparent after sharpening a knife because the tops of the hills get dirty but the valleys do not. But even without being perfectly flat the ceramic works well. It would be nice to do a side by side test to see if flattening the ceramic gives a sharper edge or not. ## Frequently Bought Together - Spyderco Ultra Fine Benchstone Sharpening Stone - 3" x 8" Ceramic Stone, Professional Grade, with Suede Carrying Case - Model 306UF - Spyderco 303MF 1" by 5" DoubleStuff Sharpening Stone - Medium & Fine Sided and Includes Protective Case - 303MF --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/49568383-spyderco-bench-stone-smart-knife-sharpener-outdoor-knife-sharpener-stone](https://www.desertcart.sn/products/49568383-spyderco-bench-stone-smart-knife-sharpener-outdoor-knife-sharpener-stone) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-23*
