SPY-204UF1 Tri-Angle Ultra Fine Stone-White, Small | Accessory stones for sharpening, refining and polishing edges

This is my first spyderco stone, and I am pretty impressed, Immediately I took it to a straight razor around the HHT1 in sharpness, With around 50 strokes randomly each side this took it straight up to HHT3 or there abouts, Following this with a strop took it up another notch. Just for trial purposes I just took this dry to my seven day growth in a fairly cold room, no pulling, no popping sounds just a clean shave. Very impressive for this antique razor. I do not have the spyderco sharp system, I bought this stone to test the stone quality, I will be testing this next by rigging it to polish a zdp stretch and see how far this alone takes it. It's already a high polish edge from other stones but not this high a grit.

Great

Exactly as ordered

Love this product and puts a lovely polished edge on ur blades

Very expensive & pointless. The fine grit in the set is very fine. This is akin to the final polish but use the knife once & it's lost the little this gives. So with that being said, don't waste your money

A very nice addition to the sharpmaker system, has taken my edges to the next level (with a little stropping afterwards of course)!

Gives an amazing edge

as other people mentioned, brings sharpness of knives to next level.

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

Obwohl ich zwei Stück gekauft habe, benötige ich nur einen. Wer Erfahrung mit der Thematik des Schärfens hat, benötigt auch nicht mehr den schwarzen Plastik-V-Ständer. Der Sharpmaker ist auch nur als Hilfe für Anfänger gedacht, die so etwas am Anfang als Einstieg in die Karriere benötigen. Erfahrene benutzen diese Steine freihand, z.B. mit der 204-freehanding Methode. Interessanterweise ist der 204UF feiner als der 302UF. Man bekommt Spiegelpolitur damit hin, fürs Entgraten benutze ich aber echtes DD57F, das genauso fein ist aber eben noch effektiver sich fürs Entgraten eignet. Der Amazonpreis schwankt täglich, bei einem günstigen Kurs ist das Produkt auf jeden Fall eine Empfehlung wert. Natürlich können nur Geübte mit so einem Präzisionswerkzeug alles herauskitzeln: hair whittling ist danach möglich. Das heisst die allerletzte und wichtigste Zutat ist das Können des Nutzers. Können ist wichtiger als dieses Produkt. Aber ohne dieses Produkt hilft einem Können auch nicht weiter. Ergo, beides wird gleichzeitig benötigt!

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

Greetings, When I utilized the Spyderco System I took a Henckels blade from the kitchen block and the Ultra Fine worked beautifully, BUT even dull, this knife has the best steel in the world as other famous names. I honed this morning an opening knife that did not give me satisfaction the day before with the standard kit, so I used the diamond pair, the standard kit and the soft edge and the result was far from my expectations. It isn't the Spyderco that poses the problem, but the steel itself. When I married we bought that set of knives for 500.$ thirty-seven years, nowadays the smallest cost 300.$. I conclusion do not expect your 20.$ knife to perform like a 300.$. Remember I told you to put the odds on your side, do not buy under 50.$; because honing is not a question of system if you are good with Arkansas and you can keep your kife properly angled, you do not change, during a race, a horse that is winning. But the thing you can not change is the quality of the metal. I saw once a Bowie for 37.$ and a few days later I stumbled on a site where the cheapest Bowie was 1,250.$. I will bet with anyone of you that the steel in the 1,000.$ was better, not only that but fancier sheath, fancier handle, autograph by Roy Rogers himself. When you hone it is the blade that matters. Your 37.$ Bowie will cut better after honing, is it worthwhile; it is forty strikes by the rod, basically with the standard kit it means 40 x 4, the complete set 40 x 8 ( the finest is only one but your knife has to hit it four times) A fine blade even rusty can be saved and will hold the cut, a shiny cheap blade will hone only your nerves. Regards, so keep your collection to the minimum and be aware that a dagger is twice the work. KEEP ON HONING! Frédérick Turgeon
