Get professional-level sharpness at home by following these simple steps:
Choose the Correct Angle:
Find the sharpening angle that matches your knife — usually 20° for Western-style knives and 15° for Japanese knives. If you’re unsure, a quick online search can help identify the right angle for your blade.
Lock the Knife in Place:
Position the knife securely against the magnetic holder to keep it stable and safe while sharpening.
Begin Sharpening:
Start with the coarse 400-grit disc and roll evenly along one side of the blade. Once complete, flip the knife and repeat the process on the opposite side.
Finish with the Fine Disc:
Use the 1000-grit disc to polish and refine the edge for a smooth, razor-sharp finish.
All Set!
Your knife is now sharper, smoother, and ready to use safely.
Our sharpener uses fine diamond abrasives to refine your knife’s edge for clean, precise cuts every time. The D35 grit creates an ideal surface for resharpening while helping protect the quality of a wide range of blades.
Our rolling knife sharpening kit ensures a flawless edge with every pass. Effortlessly guide your blade along the rotating disc for razor sharp discs at home.

The amount of time required will vary when a knife is sharpened for the first time with the Kestrel, depending on the condition of the blade and the quality of the steel. On average, it takes five minutes. The edge must first acquire the chosen 15° or 20° grinding angle. However, thanks to the
constant grinding angle, only a few rolls back and forth are needed for subsequent resharpening.
To remove grinding residue off the diamond discs, simply dab with a damp cleaning rag.
To grind particularly broad blades, where the cutting edge stands higher than the grinding disc, elevate the sharpener with a suitably thick cutting board to ensure contact with the cutting edge is within the radius of the diamond grinding disc.
Generally, western knives use the 20° angle, while Japanese knives will be 15°. To find out for specific knives, a quick Google search should give you the answer.
Our discs are made with diamond, the hardest material known to man.
When used correctly the Kestrel diamond discs shouldn't ever need replacing.
