The 10 Best Hand Knife Sharpener of 2025, Tested and Reviewed

The best type of knife sharpener depends on individual preferences, skill level, and the type of knives being sharpened. Whetstones or sharpening stones are favored by many professionals for their versatility and ability to achieve precise results. They offer control over the sharpening process and allow users to maintain the desired angle for their knives. Electric knife sharpeners provide convenience and consistency, making them popular among home cooks and busy kitchens. Guided sharpening systems, such as rod-style sharpeners or angle guides, can help maintain the correct sharpening angle for consistent results. Ultimately, the best sharpener is one that suits the user's needs and allows them to achieve the desired level of sharpness for their knives.

Are handheld knife sharpeners good?

Handheld knife sharpeners can be effective for quick touch-ups and minor sharpening tasks. They are convenient and easy to use, making them suitable for home cooks and users who prefer a straightforward sharpening process. However, handheld sharpeners may not provide the same level of precision and control as whetstones or electric sharpeners. They are best suited for maintaining the sharpness of knives between sharpening sessions rather than for reshaping or repairing severely dull edges.

What sharpener do professionals use?

Many professional chefs and kitchen staff prefer using whetstones or sharpening stones to sharpen their knives. Whetstones offer control over the sharpening process and allow professionals to maintain the desired angle for their knives. Additionally, some professionals may use honing steels or sharpening rods to maintain knife edges between sharpening sessions. Electric knife sharpeners are also used by some professionals, particularly in busy kitchens where speed and efficiency are essential.

Is an electric or manual knife sharpener better?

The choice between an electric or manual knife sharpener depends on individual preferences, sharpening goals, and the type of knives being sharpened. Electric sharpeners offer convenience and consistency, making them suitable for users who prefer a simpler sharpening process and want to achieve quick results. They are particularly useful for busy kitchens or users with limited sharpening experience. On the other hand, manual sharpeners, such as whetstones or guided sharpening systems, provide more control and flexibility over the sharpening process. They allow users to adjust the sharpening angle and customize the level of sharpness to suit their needs. Ultimately, the better option depends on factors such as user preferences, sharpening skills, and the desired level of sharpness.

Do electric sharpeners ruin knives?

When used correctly, electric sharpeners should not ruin knives. However, improper sharpening techniques or using the wrong type of electric sharpener can potentially damage knives. Electric sharpeners typically feature multiple sharpening stages, including coarse and fine grits, to restore a sharp edge to knives. It's essential to follow the manufacturer's instructions and choose an electric sharpener suitable for the type of knives being sharpened. Using excessive pressure or running the knife through the sharpener too many times can remove too much metal from the blade, leading to premature wear and reducing the knife's lifespan. Additionally, some electric sharpeners may generate heat during the sharpening process, which can affect the blade's tempering and potentially damage the knife if used improperly.
