Spyderco Tri-Angle Sharpmaker Stone, Ultra Fine Grit

I am a big fan of the Spyderco Sharpmaker system. 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!

Excellent upgrade for my Spyderco Triangle Sharpmaker. I wish it came in a TWO pack (but I just ordered another one).

I got two, for the full Sharpmaker experience. They're relatively cheap considering. If you're making the Sharpmaker your primary system, these are great to get an even finer, more precise bevel. They get a decent polish on the edge which is excellent priming for a strop to get you closer to a mirror edge. Are these mandatory? absolutely not. Are they nice to have? I think so. Definitely worth the money. I have had issues, mostly user error, lazy with maintaining my angle (yes, even with the Sharpmaker), and have completely broken off my micro burrs and destroyed my edge on some high-quality 20CV (American M390 equivalent) on an Olamic Whippersnapper. It actually left me kind of baffled. That same steel was quite prone to rolling over on a strop, but I haven't had that experience with other 20CV's, 204cp's, or M390's. These stones, like other ceramics, are prone to chipping. They are rather versatile for many, many blade shapes and are super easy to clean with a brillo pad and dish soap. I think the positives outweigh the negatives in every respect, but only if you have the Sharpmaker as your primary system.

Best money can buy. 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.

I've had a Spyderco Sharpmaker since 1990. I bought my first one at the same time I bought the then new Spyderco Endura knife. I still have that early model and keep it in the RV to keep knives sharp when traveling. I've since added the current model with the 30* inclusive feature and I've used it for years as well. Throughout that time, I never used the ultra fine Spyderco stones and I never missed them. But I had recently been considering buying into one of the other sharpening systems now available. I thought another system might improve my ability to obtain and maintain an edge on my knives. Instead, I decided to upgrade the Sharpmaker with the coarse diamond and ultra fine rods because I really like the system's simplicity. You can get a knife really sharp with the basic medium and fine ceramic stone. But you can get them just a little bit sharper with the ultra fine stones. They do need to be broken in. When new, they don't do much more than the standard fine stones. After using them for a while, you will notice how these rods add to the quality of a knife's edge. It's really evident with a new knife that has an excellent edge on it out of the box. Forty passes on the well broken in ultra fines will surprise you at how much better an already sharp edge can get. While not absolutely necessary, I still recommend these ultra fine ceramic rods for those using the Sharpmaker, especially if you have been using it for a while but you've been considering trying one of the other sharpening systems now available. You may be surprised how much better that old Spyderco system can work.

Why did you pick this product vs others?: Great for polishing of the edge and deburring. Works great with the Spyderco makesharp product, but I find that when I get to the final stage on one of the flat sides, I balance a point on a gripping mat, holding the rod loosely and running the blade down it, letting it pivot slightly, in order to keep the blade as flat as possible. Then, angling the blade slightly more to light run it a couple of times to debur it. Great results! If you are buying it for your Spyderco, you might want to buy 2 for the complete set.

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.

I have the Sharpmaker and the white stone that comes with it give all knifes a nice sharp edge. This stone brings it to the next level. There is a very noticeably difference when used - knifes are razor sharp when used properly. Could shave with my Delica if I wanted. Only ordered one and it will become a "pain" to use in the future, so will be getting another for use in the Sharpmaker. Glad I read the reviews as it lives up to them. never was I able to get a knife this sharp. I am not great at it is why I got the Sharpmaker kit and this stone just adds to the positive experience. No longer fear or hate getting a blade sharp - now razor sharp with ease. Update 12.18 - got the second stone to make it a little easier. Went on a "if it has a blade, going to sharpen it" binge. Scissors, kitchen knife's and all my pocket and EDC's. The EDC utility that I use most often (Spyderco), I found that if it starts to get a little less sharp - give it a couple of passes with these stones and I am back to razor sharp. Very little effort to get it back. Never had a pair of Scissors this sharp - I just followed the instructions in the book. Again - worth the total cost of the kit and extra stones.

Per molti anni ho usato con molta soddisfazione un affilatore Spyderco con la dotazione standard. La rifinitura era demandata a una coramella. Il tisultato finale era soddisfacente, ma non al livello di un'affilatura fatta sulle pietre, fino alla 8000. Non altrettanto efficace, sicuramente meno duratura. Queste pietre ultrafini si sono rivelate l'uovo di Colombo: comode e rapide da usare, molto più di quelle tradizionali, capaci di dare risultati se non pari almeno paragonabili a quelle e migliori della coramella. Last but not least, adeguate anche per l'affilatura dei tenacissimi acciai inox moderni, dalle durezze altissime. Unica nota dolente il prezzo, a mio giudizio ingiustificatamente più alto di quello usuale negli Stati Uniti.

Muy buen complemento para el sharpmaker, se nota la calidad spyderco, totalmente recomendado

The stones them selves are awesome but the storage tubing could be a little more sturdy.

This is a great addition to the Spyderco Sharpmaker. However I feel that most knives don’t need and won’t benefit from this high degree of honing. However, if you have a knife made from good quality steel that will hold a sharp edge this stone works great. I am disappointed that the seller doesn’t sell these in a pair. It’s like selling one sock! This makes the listing misleading. I know it only shows one stone but I thought I was ordering a pair. I had to place a second order for the other half of the pair. It’s a cheap tactic by the sell to make the price look lower than it is.

Spyderco para mí es una marca de prestigio y de alta gama en navajas cuchillos y hoy compruebo que sus piedras son de alta calidad también, luego que la recibí la probé para asentar el filo de una cold steel tuff lite que uso diario y con solo 3 pasadas la tuff lite quedó como navaja de rasurar de nuevo!! Como siempre Spyderco me dejo más que contento, Sorprendido con la chair a de cerámica!!
