I have used the Lansky system, a random crockstick system, Japanese water stones, ceramic/glass stones (like the Shapton), oil stones and Arkansas stones. I haven't used the Edgepro and some of the higher-end systems. Regardless, truth be told, I have drank the Spyderco kool-aid and love it, my knives are laser sharp in much less time than my second favorite system, which is a progression of water and Shapton stones followed by felt/leather strop with chromium oxide. So that said... I had the Sharpmaker basic kit for a while, and was reading about these ultrafine stones. The fine stones already got my better knives to pop hairs right off my arm, and my $30 Victorinox chef's knife will slice bread as well as any scalloped/serrated slicer, without crushing the bread at all and producing almost no crumbs. Veggies and chicken and other products simply don't stand a chance, every knife in my drawer will destroy them and stay sharp for weeks, even with heavy use on NSF plastic cutting boards. I've sharpened a few dozen knives and scissors and other implements for my friends, and they are amazed. So I'm reading about these ultrafine stones and had to try them out, see if they can get an edge polish equivalent to what I was achieving with much more time and effort on flat stones. Well, the hype is true. These are the real deal Holyfield. With a light touch these stones brought out a wicked sharp edge that is almost too eager to slice through anything within reach. Or maybe that's me. Just kidding. Actually, not. I had way too much fun shaving newsprint, push cutting through corrugated cardboard, making paperthin cucumber wafers, shredding my junk mail, slicing cleanly through rope, and trying out this new, sharp, durable edge on everything I could afford to have two of. haha Now this all begs the question, do you need a knife this sharp? That's a personal decision. For utility work, I'd say probably not. For industrial work, be it cutting vinyl tile or carpet or something like that, yeah it would be useful. For a butcher or wood carver or something of that nature, yes. So it really depends on your blades and what you do with them. I do believe that I can polish the edge a bit more with felt or with micron paste on horsehide to strop, which is something you would want with, say, a straight razor, which can basically never be "too sharp," as the sharper it is the less effort and pressure required. For less than an additional $30 to an already outstanding system that's under $50, I think it is money well spent. Fact is most people won't use these ultrafine stones on most of their knives all too often, so they'll last forever. Downsides? Well I certainly wouldn't drop one, as I am guessing they shatter quite easily. I do like how they are sold individually, so if one chips or breaks on you, can you replace just the one. They are easy to clean and come in a little plastic packing tube (mine did) with end caps to protect it. Some people might have a tough time getting the stone into their Sharpmaker base. Try reversing it. One side is painted red (on mine). Put that end into the base. Hope it helps! Review: Best you can get - Best money can buy.

Also, when I get to using the Ultra Fine Triangle stones, I taper off on the pressure I use, using lighter strokes the more strokes I use (although I don't have any scientific evidence to back this up, my intuition tells me that this allows the the stones to put a sharper edge on the blade). I have never been able to achieve the results shown on the videos of this sharpener being used on youtube. I got the best results with the best steel - an ESEE Izula in Damascus steel. With other steels, going from the Fine to the Ultra fine only dulled the edge. With some steels, going from the medium coarse (the dark brown stones) to the Fine dulled the edge. I don't know why this could be happening.I used the 30 degree setting on the Sharpmaker for the Izula although ESEE says the correct sharpening angle for the Izula is 20 degrees. That's the main problem with the Sharpmaker; the number of correct sharpening angles for knives is much greater than just two. Only problem is to get the exact sharpening angles, you have to go with the Wicked Edge Pro Pack I or II, and the II is $749.00. **Q: In the description it say "rods" as in 2. But the picture it shows only 1. My spyderco needs 2 rods. Which is it? Thanks** A: Oddly enough, these rods are sold individually. You need to buy 2 unless you intend to use it like a strop. Funny thing is, the diamond rods are sold in pairs. You should need only one diamond rod (profile one side at a time) . Hope this helps. **Q: Does this sell both the left and right ultra fine sharpener?** A: No, it's only one. To get the pair order two. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Outstanding Results! *by L***M on March 22, 2012* I am a big fan of the Spyderco Sharpmaker system.

Works perfect every time and will get a knife razor blade sharp. Easy to use and maintain. Had mine for years and still works like the day I got them. ### ⭐⭐⭐⭐⭐ Purchase 2 of these for your Sharpmaker kit *by C***O on March 4, 2011* Spyderco Ultra Fine Triangle Stone Although the actual "grit" equivalency for the Ultra Fine stones are hotly debated, I couldn't tell a significant difference from touch versus the Spyderco Fine triangle stones that are included in the Triangle Sharpmaker kit. That said, when using the stones, the Ultra Fine does seem to be smoother to the touch of a blade versus the Fine stones. I couldn't really find an instruction set for the Ultra Fine stones, so I used them as a "third stage" with the medium and fine grit stones that are included in the Sharpmaker kit. First off is the quantity. The stones are sold individually, so one must purchase 2 of the stones for each Sharpmaker kit. They are shipped in a clear tube to prevent damage. I noticed that my stones came with small chips which could be felt with a blade as I used them. I scrubbed the two stones together to smooth it out and it seems to have helped. These are extremely hard ceramic stones with an equivalent grit of at least 2000 or higher. They are very easy to use with the Sharpmaker kit and will give that razor-like edge to most blades. I used the Ultra Fine to put the finishing touches on a Spyderco Tenacious, a meat cleaver, pocket knife, and a letter opener. The Sharpmaker kit worked well enough on its own, but the Ultra Fine put that extra fine razor edge on the blades. Some people may not care about this part, so the standard Sharpmaker kit should suffice for most users. Overall: 5/5 stars, works as advertised, but not quite mandatory for everyone. ## Frequently Bought Together - Spyderco - Tri-Angle White Sharpening Stone with Ultra-Fine-Grit for Professional-Grade Finishing and Polishing - 204UF1 - Spyderco Tri-Angle Sharpmaker, Complete Knife Sharpening System with Medium Grit and Fine Ceramic Stones for Professional-Grade Finishing - Compact, Easy-to-Use Design - 204MF - Spyderco - Tri-Angle Diamond Sharpening Stones for Professional-Grade Finishing and Polishing - 2-Pack - 204D --- ## 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.ma/products/1481655-tri-angle-white-sharpening-stone-with-ultra-fine-grit-professional](https://www.desertcart.ma/products/1481655-tri-angle-white-sharpening-stone-with-ultra-fine-grit-professional) --- *Product available on Desertcart Morocco* *Store origin: MA* *Last updated: 2026-04-23*
