Tri-Angle stones are 7" x.5"; (178mm x 13mm) Set Contains: 1 x Spyderco Tri-Angle Ultra Fine Grit Replacement Stone Review: Finitura quasi a specchio, un po' care - 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.

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 ### ⭐⭐⭐⭐⭐ Finitura quasi a specchio, un po' care *by M***O on 12 June 2018* Per molti anni ho usato con molta soddisfazione un affilatore Spyderco con la dotazione standard.

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! ## 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? - 🛒 **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.co.za/products/266772408-spyderco-tri-angle-white-sharpening-stone-with-ultra-fine-grit](https://www.desertcart.co.za/products/266772408-spyderco-tri-angle-white-sharpening-stone-with-ultra-fine-grit) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-11*
