What is a knife sharpener?

A knife sharpener is a tool designed to restore or maintain a sharp edge on a knife's blade either by removing the metal to reshape the edge or by realigning the existing edge to reduce dullness.

Whetstones

Our traditional whetstones offer precision and control for sharpening any blade to a razor fine edge. Available in a range of grits, they’re ideal for restoring dull knives and fine-tuning your edge. The favourite sharpening method of Japanese chefs and knife enthusiasts who want full control over their sharpening process.

Roller Sharpeners

For fast, consistent results, our roller sharpener makes sharpening effortless. Featuring guided angles and durable sharpening disks, it’s perfect for home cooks who want professional-level sharpness without the learning curve of a whetstone.

Sharpening Steels

Maintain your edge between sharpenings with our honing steels. Designed to realign and hone the blade after regular use, they’re an essential everyday tool for keeping your knife performing at its best.

Shop the Katana Saya kitchen knife sharpening collection and keep every blade in your kitchen performing at its sharpest.

Knife Sharpening FAQs

A whetstone is a sharpening stone used to grind and reshape a dull blade's edge, offering the most control and precision - it's the traditional method preferred by professional chefs. A roller sharpener uses guided angles and sharpening wheels to quickly restore an edge with minimal skill required. A sharpening steel doesn't sharpen the blade itself but realigns and hones the edge between sharpenings, helping maintain sharpness for longer.

This depends on how often you use your knife but most home cooks should sharpen their kitchen knives every 1-3 months with a whetstone or roller sharpener. Sharpening steels should be used more frequently, ideally every few uses, to maintain the edge between full sharpenings.

For the best results, yes. A whetstone or roller sharpener are used to periodically sharpen and restore the blade's edge, while a sharpening steel is used regularly between sharpenings to keep the edge aligned and performing well. Using both together helps to extend the overall life of your knife.

Yes, the Katana Saya Roller Sharpener is designed to work safely with Damascus steel and other high-quality steels, using guided angles to protect the blade's edge and pattern while delivering a consistent and precise sharpen.

No. A sharpening steel realigns and straightens the blade's edge but doesn't remove the metal or restore a truly dull blade. For a knife that has lost its sharpness, use a whetstone or roller sharpener to properly resharpen the edge, then use a sharpening steel for ongoing maintenance.

Coarse grits (400-1000) are best for repairing damaged of very dull blades. Medium grits (1000-3000) are ideal for regular sharpening and maintenance. Fine grits (3000+) refine the edge to a razor-sharp finish. Most kitchen knives only need a medium to fine grit for everyday sharpening.

If your knife struggles to cleanly slice through tomatoes or other soft food, or if you notice it slipping rather than cutting, it's time to sharpen. Regular honing with a sharpening steel can delay the need for a full sharpen, but even well-maintained knives will need resharpening over time.
