Rolling Knife Sharpener with Multi-Functional Magnetic Angle Base Why you need it Keeps a constant sharpening angle for repeatable, precise results so blades cut cleaner and stay sharper longer. Two selectable angles let you match the edge to the task: 15 degrees for ultra-fine slicing and high sharpness, 20 degrees for a tougher, more durable edge. Magnetic tool holder secures the blade during sharpening for safer, more accurate strokes. Key features and benefits Double grinding angle: built-in magnetic angle base offers 15 degrees and 20 degrees to suit fine kitchen work or heavy-duty use. Consistent performance: the rolling action maintains a steady angle throughout sharpening, reducing guesswork and uneven edges. Broad material compatibility: effective on stainless and high-carbon steels, including Damascus blades and other hard steels. Compact and durable: stainless steel construction and a compact footprint for stable use and easy storage. Simple operation: choose the angle, secure the blade with the magnetic holder, then roll the sharpener back and forth until the edge is restored. Practical applications Culinary precision: restore and maintain the fine edge needed for sushi, sashimi, and other delicate slicing tasks. Outdoor and field use: sharpen hunting and survival knives while camping or in the field for reliable cutting performance. Specialty blades: recover the cutting ability of Damascus and high-carbon knives used for fine or heavy-duty cutting.
