"Working edge" being the key. Don't expect a 1000 grit to give you razor sharp hair popping edges, but this stone will get them pretty darn sharp... I use this one to get my edges sharp and profile quick, from standard stainless kitchen Knives to pocket knives made with premium super steels, this stone's medium side will reprofile most dings and such in a badly dulled blade, the fine side will get a good working edge on anything. Then with a nice sharp edge set, for shaving sharp edges I take them to a 2000/5000 water stone to polish them even finer...

So far it has stood up well and still sharpens chisels and plane irons well, though the coarse side has discolored a little bit, I am not sure if that is rust or something else. ## Frequently Bought Together - Ultra Sharp XL Double-Sided Diamond Sharpening Stone | Coarse and Extra Fine Grit - SHAPTON Ha No Kuromaku Ceramic Whetstone (A-set) Medium Grit (#1000) + Fine Grit (#5000) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/23358950-ultra-sharp-xl-double-sided-diamond-sharpening-stone-300-1000](https://www.desertcart.vu/products/23358950-ultra-sharp-xl-double-sided-diamond-sharpening-stone-300-1000) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-02*
