## Overview

Spyderco’s Tri-Angle Diamond Sharpening Stones deliver professional-grade edge restoration with diamond-coated abrasives engineered for aggressive stock removal and precise reshaping. Designed to fit the 204 Sharpmaker system, these durable steel stones clean easily and sharpen all blade types, including serrations, making them an essential upgrade for any serious knife enthusiast or professional.

## 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: 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.

## 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.

This additional set of sharpening "stones" for the Spyderco Tri-Angle Sharpmaker (actually they are a pair of hollow steel triangles coated in industrial diamonds) sorted out knives that were particularly dodgy (having been through the AnySharp Knife Sharpener -- not recommended!). A worthwhile addition to the main device.
