Designed to fit the 204 Sharpmaker system, these stones aggressively remove stock to re-shape, re-bevel, and polish all types of edges—including serrations—with ease. Lightweight and easy to clean, they deliver rapid, precise sharpening that transforms dull blades into razor-sharp tools in minutes. ## Description These steel triangle stones are blanketed in a bonding agent, then covered in diamond particles. Diamond hard abrasives are recommended when you wish to remove stock, for restoration purposes and to aggressively re-shape, re-bevel and re-profile a cutting edge. Sold in a pair, 204D triangles fit into the 204 Sharpmaker sharpening system. To Clean: rinse in freshwater. Review: Coarse 220 grit, works well for re-beveling knives - This is the missing part of a Sharpmaker. The brown stones don't cut aggressively enough to remove nicks or change the profile angle of an edge. What would take an hour with the brown stones is a few minutes with these. I use the large DMT diamond plates for sharpening woodworking tools, so I'm used to not using heavy pressure. Some reviewers have said the diamonds fall off. Not for me with light pressure. Once you have used diamonds, you will quickly grow impatient with anything else for coarse sharpening. I use the diamonds, then side of brown stones, then side of white stones. I don't use the edges for anything except serrations if they fit, or the occasional hooked blade. It is true you can buy a nice diamond plate and a 4000 grit Shapton glass stone for about the same money as this plus the sharpmaker, but for ease of use I would recommend this for knives (not chisels or other woodworking tools of course). It's much easier to hold the knife vertically than to try to maintain an angle on a horizontal plate. Some people have built stands to hold their stones or plate at a similar 15 or 20 degree from vertical angle, if that appeals to you. If you are only going to sharpen short pocket knives, an alternative is to buy the lansky-style DMT aligner sharpening kit and get the optional ceramic stone for it if you want a polished edge. In addition to learning to feel for the burr and maintaining a constant angle, it's helpful to have a 10x triplet magnifier and look at the edge after each sharpening step. I see plenty of you tube videos where people will go through six waterstones in a ritual to get an edge, when a few more strokes on half that would remove any scratches with much less time. Look at videos from knife makers, not users - they don't waste time. Review: Optimal für Schleifwinkel größer 40 Grad - Hallo, ich besitze nun seit Jahren den Spyderco Sharpmaker. Leider konnte ich diesen bisher nur eingeschränkt einsetzen, nicht ohne Grund trägt das Produkt inoffiziell den Namen "Sharpkeeper". Das Problem ist nämlich, dass sehr stumpfe Klingen, vielmehr aber Klingen mit einem größeren Schleifwinkel als 40 Grad, nicht effizient mit den zwei unterschiedlichen Körnungen des Sharpmakers geschliffen werden können. Es wird einfach zu wenig Material abgetragen, sodass zum Beispiel bei einem Messer mit 50 Grad nur an den Seiten geschliffen wird, nicht aber unten an der Klinge, wo man einen Grat erreichen möchte. Da der Sharpmaker nur maximal 40 Grad Winkel untersützt, muss man also die Klinge auf 40 Grad schleifen und demzufolge sehr viel Material abtragen. Das funktioniert mit den Diamant-Schleifsteinen super! Ich konnte mit diesen Messer in 10 Minuten auf eine Grundschärfe bringen und endlich einen Grat herstellen. Dazu sei gesagt, dass ich nicht die offizielle Schleiftechnik benutze, sondern für mehr Materialabtragung ungefähr 40 Mal auf einer Seite schleife und hierbei auch mit Kontakt am Stein hochziehe statt nach dem herunterdrücken abzusetzen und neu anzulegen. Danach wechsel ich die Seite und folge daraufhin der Anleitung und schleife wie gewohnt abwechselnd. Kleiner Tipp: um festzustellen, ob man auf einer Seite genug Materiel abgetragen hat kann man mit einem Filzstift die Schneide markieren, wenn die Farbe bis zum Grat weggeschliffen wird kann man aufhören. Auch liegt dem Produkt ein Warnhinweis bei ausdrücklich darauf hinweist, nicht zu viel Druck auf die Klinge auszuüben, da sich sonst die Diamantstückchen lösen können. Mit leichtem Druck wird auch genug Material abgetragen. Ich kann die Diamantsteine nur wärmstens empfehlen, diese sind ein absolutes Muss für jeden Sharpmaker-Besitzer, ohne diese kann man stumpfe Messer nicht effizient schärfen. ## Features - DIAMOND COATED - These steel triangle stones are blanketed in a bonding agent, then covered in diamond particles - PROFESSIONAL-GRADE - Diamond hard abrasives are recommended when you wish to remove stock, for restoration purposes and to aggressively re-shape, re-bevel and re-profile a cutting edge - MULTIFUNCTIONAL - Sharpen all types of edges including serrated edges and fits into the 204 Sharpmaker Sharpening System - EASY TO CLEAN - Simply rinse with fresh water and let the product air-dry - SPECIFICATIONS - Sold as a pair, Overall Length (Inches): 7, Coating: Diamond ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000WUKFBM | | Best Sellers Rank | #220,512 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #425 in Sharpening Stones | | Brand | Spyderco | | Brand Name | Spyderco | | Color | White | | Colour | White | | Customer Reviews | 4.6 out of 5 stars 605 Reviews | | Global Trade Identification Number | 00716104640164 | | Grit Type | Very Fine | | Grit type | Very Fine | | Included Components | see descritption | | Item Dimensions L x W x H | 13L x 13W x 178H millimeters | | Item Type Name | Spyderco Diamond Triangle Pair 204D | | Item Weight | 0.15 Pounds | | Item weight | 0.15 Pounds | | Manufacturer | Spyderco | | Manufacturer Part Number | 204D | | Material | Steel | | Material Type | Steel | | Model Number | 640164 | | Number of Items | 1 | | Product dimensions | 13L x 13W x 178H millimeters | | UPC | 716104640164 716104640607 | | Unit Count | 1 Count | ## Product Details - **Brand:** Spyderco - **Colour:** White - **Item weight:** 68 g - **Material:** Steel - **Product dimensions:** 13L x 13W x 178H millimeters ## Images ![Spyderco - Tri-Angle Diamond Sharpening Stones For Professional-Grade Finishing And Polishing - 2-Pack - 204D - Image 1](https://m.media-amazon.com/images/I/519wEoibFFL.jpg) ![Spyderco - Tri-Angle Diamond Sharpening Stones For Professional-Grade Finishing And Polishing - 2-Pack - 204D - Image 2](https://m.media-amazon.com/images/I/61OQVmlIzYL.jpg) ![Spyderco - Tri-Angle Diamond Sharpening Stones For Professional-Grade Finishing And Polishing - 2-Pack - 204D - Image 3](https://m.media-amazon.com/images/I/618zHxyEpoL.jpg) ![Spyderco - Tri-Angle Diamond Sharpening Stones For Professional-Grade Finishing And Polishing - 2-Pack - 204D - Image 4](https://m.media-amazon.com/images/I/6158oIf9AGL.jpg) ## Questions & Answers **Q: Should I buy the diamond rods for this?** A: Pablo, the only time you need the Diamons rods is if your planning on changing the angle of the bevel. Lets say you are trying to sharpen at 20 degrees per side, but when you use the other stones, you notice your stones are not touching the apex of the blade. Then you would need the diamond stones to set a new bevel to match the proper degree required. The diamond stones does this job fairly fast and incredibly well. Hope this helped, if you have any more questions. Post and Ill try to help! **Q: Will this sharpen ceramic blades?** A: No, this would destroy a ceramic blade. These are very rough and are designed to take off a lot of metal when reprofiling a blade. Ceramic is too delicate. **Q: What is the Micron of these stones and grid if you have any information? Thank You Have a great day!** A: i dont know the micron for the diamond stones the grid is 400 microns for the medium stone is 20 fine 9 ultra fine7 hope it helps you **Q: Are these poly-diamond infused of mono-diamond infused?** A: The spyderco catalog for this product (204D) doesn’t specify, you may check the the bladeforums site for extensive discussion. I’ve found them effective on my harder steels like S35VN and S90V. My Benchmade 940-1 in S90V came dull as a butter knife and forty or so swipes on these diamond rods got it pretty well on its way to shaving. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Coarse 220 grit, works well for re-beveling knives *by R***E on 4 August 2019* This is the missing part of a Sharpmaker.

A worthwhile addition to the main device. ## Frequently Bought Together - Spyderco - Tri-Angle Diamond Sharpening Stones for Professional-Grade Finishing and Polishing - 2-Pack - 204D - 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 --- ## 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.hr/products/260143580-spyderco-tri-angle-diamond-sharpening-stones-for-professional-grade-finishing](https://www.desertcart.hr/products/260143580-spyderco-tri-angle-diamond-sharpening-stones-for-professional-grade-finishing) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-09*
