Aoibox Knife Sharpening Angle Guide 3 Piece Set for Whetstone with Ceramic Protective Layer 15 Degrees Tool

This set includes 3 knife sharpening angle guides, each measuring 100 mm (3.93 in.) long and 20 mm (0.78 in.) wide, designed to clamp onto knife spines and maintain a consistent 15-degree sharpening angle during whetstone use. Each guide features a 2-sided ceramic protective layer that shields the knife spine from scratching while ensuring safe, durable contact during extended sharpening sessions. The clamp design grips knife spines up to 4 mm in thickness securely without slipping, keeping the blade at the correct angle throughout the entire sharpening stroke. Consistent angle maintenance is critical to achieving a sharp, uniform edge across the full blade length, and these guides simplify that process for both experienced sharpeners and beginners. Having three guides in the set allows.
