SULLARYA Rolling Knife Sharpener with Diamond & Ceramic Discs — 15°/20° Magnetic Angles, Two-Stage Polishing

The SULLARYA Rolling Knife Sharpener is a two-stage, magnetic sharpening system that quickly restores a precise 15° or 20° edge using a diamond disc for reshaping and a ceramic disc for polishing.

Keep knives performing like new without complicated rigs or power tools. This compact sharpener combines a rigid wooden base with neodymium magnets and two abrasive discs so you can set a consistent angle and roll to a keen, long-lasting edge. It works for a wide range of straight-edged kitchen blades—from delicate Japanese gyutos to sturdy Western chef's knives—while minimizing metal removal compared with common pull-through devices.

How does the two-stage diamond and ceramic system improve blunt blades?

The coarse diamond disc (#400 grit) quickly reshapes worn or nicked edges by removing dull metal, then the fine ceramic disc (#3000 grit) refines and polishes the bevel to a smooth, razor-ready finish. This sequential approach reduces sharpening time while promoting a cleaner cutting performance.

• #400 diamond reshapes and repairs chips.
• #3000 ceramic hones and polishes to a mirror edge.
• Two-stage process removes only necessary material to extend blade life.
• No oils, no water mess, and no power required.

Which knives fit the 15° and 20° angle settings?

Choose 15° for Japanese-style knives that require a finer, more acute bevel, and 20° for Western chef's knives, santoku, paring, and utility blades that benefit from a more durable edge. The magnetic docking system centers the blade and preserves a uniform angle throughout each roll.

• 15°: sushi, yanagiba, and fine-edge Japanese blades.
• 20°: chef's knives, santoku, paring, and general-purpose knives.
• Not intended for serrated edges or scissors.
• Magnets stabilize blade for consistent sharpening passes.

How safe and stable is the magnetic base during sharpening?

Four strong N48 neodymium magnets lock the blade in place so the sharpener operates without slips or angle drift. The beech wood base adds weight and friction against countertops, keeping the unit stationary and reducing the risk of accidents while you roll.

• Four N48 magnets secure knives firmly to the base.
• Solid beech wood base prevents sliding and wobbling.
• Ergonomic rolling motion keeps hands away from the edge.
• Compact footprint fits on counters or in drawers when stored.
