Best Knife Sharpeners

A dull blade is the most common reason home cooking feels harder than it should, and the right knife sharpener fixes that in minutes. Whether you own a German chef’s knife, a Japanese santoku, or a drawer full of mismatched blades, a good sharpener restores a clean edge that bites into tomatoes and glides through onions without crushing them. Below are five sharpeners that consistently earn their place on the counter, from full electric systems to compact manual options.

Top Picks

1. Chef’sChoice 15 Trizor XV

This three-stage electric sharpener is a longtime favorite because it can convert a standard 20-degree European edge into a sharper, more durable 15-degree edge. The diamond abrasives do the heavy shaping, while the stropping stage polishes the edge so it feels noticeably keener. It is the easiest pick for someone who wants one machine to handle most of their knives.

2. Chef’sChoice 15XV Professional

Mechanically similar to the Trizor, the 15XV emphasizes a durable metal housing and the same 100 percent diamond abrasives. If your knives already run at a 15-degree angle, or you want them there, this model keeps that geometry consistent pull after pull.

3. Work Sharp Culinary E5

The E5 uses guided slots and timed cycles to sharpen straight blades, serrated knives, and even kitchen shears. A built-in vacuum collects metal dust, which is a small touch that keeps your counter clean. It is a smart choice for a household with many different blade types.

What to Look For in a Knife Sharpener

Start with the abrasive. Diamond abrasives cut hard steels quickly and last a long time, which is why most premium electric sharpeners use them. Next, consider the sharpening angle. European knives are traditionally ground around 20 degrees per side, while Japanese-style knives favor a finer 15 degrees. A sharpener that matches or can convert to your preferred angle will give you the best results. Finally, look at the number of stages. A coarse stage shapes the edge, a medium stage refines it, and a stropping stage polishes it for a smoother final cut.

Electric vs. Manual Sharpeners

Electric sharpeners are forgiving and fast. They use motorized abrasive wheels and guide slots that hold a consistent angle, so even a beginner can get reliable results. The trade-off is that aggressive electric units remove more metal over time. Manual pull-through sharpeners and whetstones give you more control and remove less steel, but they demand practice and patience. Many cooks keep an electric sharpener for periodic full sharpening and a steel or manual tool for daily touch-ups.

How to Sharpen Safely and Maintain the Edge

Always pull the knife through with light, even pressure and let the abrasive do the work; pressing hard only wears the blade faster. Wipe the knife after sharpening to remove metal residue, then test the edge on a piece of paper. To keep that edge longer, use a honing steel a few times a week, cut on wood or plastic boards rather than glass or stone, and hand-wash your knives.

Who Should Buy Each Type

If you own a mixed set of European knives and want the simplest path to a sharp edge, an electric sharpener like the Trizor XV is the easiest answer because it controls the angle for you. Cooks who have invested in Japanese knives, or who enjoy the craft of sharpening, often prefer whetstones for the control they offer, and may use an electric sharpener only as a backup. Households with shears, serrated bread knives, and steak knives benefit from a versatile unit like the Work Sharp E5 that handles multiple edge types in one machine. Finally, if counter space and budget are tight, a compact unit such as the E2 Plus or a handheld manual sharpener delivers a usable edge without dominating the kitchen. Match the tool to your knives and your patience, and you will use it far more often.

Common Sharpening Mistakes to Avoid

The biggest mistake is over-sharpening: running a knife through the coarse stage every time removes metal you do not need to lose and shortens the blade’s life. Reserve coarse grinding for truly dull or chipped edges, and rely on the fine and stropping stages for routine upkeep. Pressing too hard is another frequent error; the abrasive works best with light, consistent pressure. Skipping the honing steel between sharpenings means your edge dulls faster than it should, since regular honing keeps the thin edge aligned. And washing knives in the dishwasher undoes your work, as the heat, detergent, and jostling against other items dull and even chip the edge.

Frequently Asked Questions

How often should I sharpen my knives?

Most home cooks need a full sharpening every few months, depending on use. Honing with a steel between sharpenings keeps the edge aligned and extends the time between sessions.

Can these sharpeners handle serrated knives?

Some can. The Work Sharp Culinary E5 has a dedicated path for serrated edges, and several Chef’sChoice models include a stage for serrated blades. Always check the product details before sharpening a serrated knife.

Will an electric sharpener ruin my expensive knives?

Used correctly, no. Follow the recommended angle and let the machine pull the blade through without forcing it. For very high-end Japanese knives, many owners prefer whetstones for maximum control.

What angle should my kitchen knives be sharpened to?

European knives are commonly 20 degrees per side, while Japanese-style knives are often 15 degrees. A sharper angle cuts more cleanly but can be slightly less durable for heavy chopping.

Do I still need a honing steel if I own a sharpener?

Yes. A honing steel realigns the edge between sharpenings and keeps your knife performing well for longer, so the two tools complement each other.
