This ultra fine grit stone is triangular for sharpening plain edges on the flat sides and serrations on the corners. A furrow running the length of each stone lets you sharpen pointed items like fishhooks, darts and awls.

Ultrafine stones tighten the blade's scratch pattern to an even keener degree for hair-popping professional sharpness and polishing.

TriAngle stones are 7"x.5" (178mm x 13mm). Sold Individually.

This item is designed for use with the Spyderco Triangle Sharpmaker.

The difference isn't huge by any means, but it does get it to that next level. It's worth it if you obsess over having the very best possible edge you can achieve with the system. Using the boron more frequently I can say it's useless, I reviewed it there but honestly it's bad, don't buy that, didn't fit so I forced it and how the other ones wobble around slightly. Already wore out on me and I followed what was said. But this fits fine. If you are to buy another stone grab this one, DO NOT BUY THE BORON ONES.

You don't really need two of these if you pay attention to the burr and switch positions. With one, you have a great value but less convenience, and with two you have convenience at the cost of a more expensive system.

This is one of the most useful stones for the package, and is the only upgrade I see necessary to the Sharpmaker. Diamond and the CBN stones are not worth the investment, and if such equipment is necessary look into KME for all of its benefits, or just get a lansky with diamonds. I personally use a worksharp to set the angle, and finish on the Sharpmaker.
