Most Knife Sharpeners Are Ruining Your Blades
Electric Sharpeners
They remove too much steel too quickly and overheat the blade edge. Once that damage is done, your knife never performs the same again.
Pull-Through Sharpeners
These rip metal off your blade with every pass. They’re fast, aggressive, and permanently shorten the life of your knives. You’re not sharpening—you’re grinding them down.
Whetstones
Effective, but difficult to master. One wrong angle can ruin an edge, and inconsistent pressure leads to uneven, unreliable results. Most people never get it right.

Which angle is best for my knife: 15° or 20°?
+
The 20° angle creates a strong, durable edge that’s ideal for everyday kitchen use and outdoor tasks. It sharpens quickly and delivers a long-lasting edge suited for tougher cutting jobs.
The 15° angle is designed for precision, producing a finer, sharper edge that’s best for Damascus and high-quality carbon steel knives—perfect for delicate, detailed cuts.
Quick Guide
20° Angle
(Strong & Durable Edge)
• Western kitchen knives (e.g., chef’s knives, utility knives)
• Everyday stainless steel knives
• Outdoor and survival knives
• Pocket knives
• Hunting knives
15° Angle
(Precision & Fine Edge)
• Japanese kitchen knives (e.g., santoku, nakiri)
• High-quality carbon steel knives
• Damascus steel blades
• Fillet knives
• Specialty or delicate knives needing a sharper, thinner edge
These recommendations serve as general guidelines. For best results, refer to your knife manufacturer’s specific angle recommendations when available.
How often should I sharpen my knives?
+
RollSharp© Magnetic Knife Sharpener delivers a powerful balance of simplicity, precision, and professional-grade sharpness—outperforming traditional sharpening tools and services.
Compared to a Honing Rod
Honing rods help maintain an edge by realigning the blade, but they don’t actually sharpen it. RollSharp© uses a diamond-coated sharpening surface to perform true sharpening, restoring dull knives to like-new sharpness.
Compared to Pull-Through Sharpeners
Pull-through sharpeners may be fast, but they often remove excessive material, shortening blade lifespan. RollSharp© features a smooth rolling action and magnetic angle control, ensuring consistent sharpening without unnecessary wear.
Compared to Whetstones
Whetstones can produce excellent results, but they require time, practice, and precise technique. RollSharp© delivers whetstone-level precision with preset angles, making professional results achievable in minutes—even for beginners.
Compared to Professional Sharpening Services
Professional services can be effective, but they cost time and money, and you’re without your knives while they’re serviced. RollSharp© lets you achieve comparable, pro-level sharpness at home whenever you need it—no waiting, no hassle.
What is your warranty and return policy?
+
Yes! All RollSharp© Magnetic Knife Sharpeners come with a 100% satisfaction guarantee and a 30-day money-back promise (extended through the holiday season). Each sharpener also includes a warranty against manufacturing defects, so you can sharpen with confidence knowing you’re fully covered.
