Spyderco SPY-204UF1 Tri-Angle Ultra Fine Stone-White, Small

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.

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

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

Gives an amazing edge

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

I purchased a pair of the Ultra Fine stones for my Spyderco Sharpmaker, I am really pleased with them. Many thanks.

It sharpwn ur edge to new level

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

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.

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.
