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: Spyderco Diamond Rod, does the job on dull serrated blades - I have had the Spyderco ceramic sharpener kit for many years, about 20. They work fine for most of my pocket serrated and straight edge knifes , if not too dull. For fine knifes I prefer to use a larger flat Arkansas stone. I got these diamond rods mostly for my serrated kitchen knifes, some of which were ignored for a while. The ceramic rods that came with a kit just required too much time and patience to sharpen . My hand hurt afterwords. I was going to send them to Wusthof to sharpen, but now during CV19 crisis they are closed. So I looked around and found these, new to me diamond rods. I read the reviews and was a bit concerned about the fit. No issues the uncoated end fits just like the original ceramic rods. I used them with about the same touch as ceramic rods holding the knife lightly and stroking down gently as if I wanted to whittle a piece off. The grit on these felt about like a 400 sandpaper, much more aggressive than the ceramic rods which are used best on semi sharp knifes to hone them. No problems with diamonds coming loose, that would take gorilla strokes. It helped to restore old serrated knifes and then I honed them with the ceramic rods. Now I will use the ceramic rods more frequently on them, mostly the brown one. I also use the honing steel rod that came with the knife set after every use, to smooth the edge. ## Features - Aggressive Sharpening Power: Diamond-coated triangular rods quickly remove steel to reshape dull or damaged edges, restoring with minimal effort and precision - Optimized for Sharpmaker System: Engineered specifically for Spyderco's Tri-Angle Sharpmaker, these stones easily sharpen plain edges, serrations, and specialty blades with enhanced versatility and edge control - Long-Lasting Diamond Coating: Industrial-grade bonded diamond abrasives offer consistent cutting performance and extended wear resistance, delivering reliable sharpening over years of regular use - Simple to Use and Maintain: No messy oils needed-just clean with water and let the product air-dry; the triangular shape allows for sharpening a wide range of angles, grooves, and edge types without hassle - Includes Matched Stone Pair: Comes with two matching 7-inch diamond rods for balanced and uniform sharpening, essential for users seeking a fast, coarse grit stage in their sharpening workflow - Professional-Grade Performance: Durable steel core construction bonded with ultra-hard diamond abrasives provides maximum surface contact for efficient re-shaping, re-profiling, and re-beveling of cutting edges including serrated blades ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000WUKFBM | | Best Sellers Rank | #119,967 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #188 in Sharpening Stones | | Brand | Spyderco | | Brand Name | Spyderco | | Color | White | | Customer Reviews | 4.7 out of 5 stars 629 Reviews | | Global Trade Identification Number | 00716104640164 | | Grit Type | Fine | | Included Components | Product | | Item Dimensions L x W x H | 0.51"L x 0.51"W x 7.01"H | | Item Type Name | Holster | | Item Weight | 2.4 ounces | | Manufacturer | Spyderco | | Manufacturer Part Number | 204D | | Manufacturer Warranty Description | 2 Year Manufacturer | | Material | Diamond | | Material Type | Diamond | | Model Number | 640164 | | Number of Items | 1 | | Product Dimensions | 0.51"L x 0.51"W x 7.01"H | | UPC | 716104640164 716104640607 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Spyderco - **Color:** White - **Grit Type:** Fine - **Item Weight:** 2.4 ounces - **Manufacturer:** Spyderco - **Material:** Diamond - **Number of Items:** 1 - **Number of Packs:** 2 - **Product Dimensions:** 0.51"L x 0.51"W x 7.01"H - **Unit Count:** 1.0 Count ## Images ![7" Tri-Angle Sharpmaker Stones, Diamond Grit | Quick Steel Removal, Sharpening Abrasive Rods for Tri-Angle Sharpmaker System, 2-Pack - Image 1](https://m.media-amazon.com/images/I/519wEoibFFL.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 August 4, 2019* This is the missing part of a Sharpmaker.

I have been a faithful user of this kit since 1992. This kit is worth the money: no oil, straightforward and simple to use. If your knife hasn’t been sharpened in a while, or you have the newer, super hard steels, this makes short work of putting an edge on your knife. What would take hours on the medium stones takes minutes on the diamonds. The simple caveat is don’t bear down while using them. A smooth, steady, even, light pressure is all it takes. No muscling is needed. The diamond rods won’t get your knife sharp alone: they will make it very easy to use the medium and fine stones to get a razor edge. Worth the money. They take all the work out of getting a great edge. ## 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.jp/products/2233341-7-tri-angle-sharpmaker-stones-diamond-grit-quick-steel-removal](https://www.desertcart.jp/products/2233341-7-tri-angle-sharpmaker-stones-diamond-grit-quick-steel-removal) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-09*
