The Blue Oval sharpening rod is perfect for fine sharpening as well as for keeping particularly hard knives sharp. The handle is ergonomically shaped and has an eyelet for hanging. The metal toggle prevents unintentional rolling off the work surface and protects the hand while sharpening.
The oval shape of the oxide ceramic allows additional variation of sharpening pressure by simply turning the rod. The wide face of the oval grinding surface exerts less pressure on the blade than the narrow grinding surface.
The blue ceramic is sintered, making it harder than any steel knife. It optimizes kitchen knives in fine grinding with a grain size of F360/J800.
