The forth triangular ceramic hone is especially designed for serrated blades. In addition to the four hones, our diamond kit comes with blade vice, hone rods, oil, and durable plastic carrying case. When sharpening with the diamond hones, lubricate the hones with water instead of oil. If you already have a Lansky knife sharpening system, you probably don't have the ceramic triangular hone for your serrated blades. Upgrade now so you can sharpen ALL your knives.
Hone includes guide rod.
This tapered diamond coated steel rod folds into its own handle for storage like a butterfly knife. It's an excellent sharpener for your Spyderco serrated knives as well as any other serrated or plain edge knife. Fast, easy durable and easy to toss into your tool bag. When sharpening a serrated blade, choose the thickness of the rod that matches your knife blade serration and push the sharpener forward. That's all there is to it.
