Best Serrated Knife Sharpeners of 2026

Every other pick here pulls the blade through a fixed slot. This one is a rod, and the shape is the entire point: the tapered diamond-coated end is narrow enough to sit down inside a single scallop and work it, which is the only way to bring back a serrated edge that has worn unevenly. The flat section handles plain blades, so it covers both jobs in one handle.

We like it best as a companion rather than a complete sharpening kit. The diamond is coarse grit, so it moves metal with a light touch, and the rod retracts into the handle — the same tool that fixes a steak knife indoors will touch up a fillet knife at the water. For a household where one bread knife gets an occasional pass, that is plenty of sharpener.

Small also means slow. You are working one scallop at a time with short strokes, and a long bread knife takes patience that a pull-through never asks for. If you have a whole block of serrated knives to bring back from the dead, start with the AccuSharp and finish here.

This is the only corded machine in the set, and it is priced like an appliance rather than a gadget. What that buys is a 4.2-pound countertop unit with three diamond stages and patented spring guides that hold the bevel for you: no stroke to learn, no wrist angle to guess, no way to end up sharpening at 22 degrees because you were in a hurry.

The 15-degree output is the interesting part. Most Western kitchen knives leave the factory at 20 degrees; the EdgeSelect regrinds them to a narrower Trizor XV edge that goes through tomatoes and crusty bread with noticeably less effort. Serrated blades go through the stropping stage for a light hone rather than a full regrind, which is the right call for keeping the teeth intact.

The edge it produced was the most refined of anything we tried here, and it got there in a fraction of the time the manual tools took. The costs are real, though: it occupies about ten inches of counter and weighs 4.2 pounds, and the guides can scuff the polished faces of a blade if you let the knife ride against them. Keep a firm, level draw and check the flats after the first knife.

Eight ounces of gray plastic, and it holds a bevel better than we can by hand. Two diamond stages with fixed angle guides take a knife from dull to clean in under a minute, and the CrissCross wheel arrangement works both sides of the edge at once so the burr comes off evenly. No oil, no soaking, no ten-minute setup on a stone.

The footprint is what sold us. At 9.25 inches long and 2 inches wide it drops into the knife slot of a drawer, which is where a sharpener has to live if it is going to get used more than once. It handles 15- and 20-degree knives depending on which guide you use, and serrated blades belong in the fine stage only — the coarse side will chew the teeth flat if you let it.

What you give up is heft. The body feels light and plasticky in the hand for something in this price range, and it is not the tool you hand down to anyone. It is the tool that sharpens every knife in the kitchen this year, which is the job.

The notch molded into the base is the whole idea. Hook it over the edge of a counter or table and the sharpener braces there, so a long bread knife can be drawn all the way past the tip without the point dragging across your countertop — the exact annoyance that makes most compact sharpeners maddening with a blade longer than six inches.

Two stages do the work: carbide to reset a beaten edge, ceramic to polish off what the carbide leaves. Three or four strokes in the coarse slot brings a soft steak knife back to cutting rather than crushing, and the non-slip foot keeps the whole thing planted while you pull.

The catch is the size. At 3.75 inches tall there is not much body to hold, and a long blade torques the unit if you rush the stroke, so you slow down and use your other hand. That is a fair trade for something that stores in a utensil drawer and costs less than almost anything else here.

Four slots, and one of them is set aside for serrated blades — that is the reason this one made the list. Coarse carbide reshapes, a medium and a fine ceramic polish, and the serrated setting changes the angle for toothed blades instead of asking you to find it yourself.

A thumb dial switches between grits without lifting the sharpener off the counter, and the rubberized base stays planted through a full stroke. We noticed that more than we expected to. Most of the pulling happens with one hand while the other holds the body down, and not having to reset the thing every few strokes changes how often you bother.

Results were the least consistent of the manual sharpeners here. Some blades came back with a clean, almost polished edge; others needed far more passes to show any change, and the coarse side leaves a wire edge if you stop there. It is a good second sharpener for a mixed drawer of everyday knives, not the one to hand someone whose only serrated knife is a good bread knife.

Fifteen degrees is the bevel a lot of Japanese and gourmet knives are ground to, and this is the inexpensive hand-held that respects it. It is the same idea as the standard AccuSharp, shortened to 5.5 inches and set to a narrower angle, with reversible diamond-honed carbide blades.

If your serrated knife is a Shun or a Global, or anything else in the 15-degree class, running it through a 20-degree slot undoes the geometry you paid for and takes a lot of metal with it. This one does not. The trade is handle: 5.5 inches and 1.6 ounces means less to hold onto, and a long bread knife takes more passes than it does with the full-size version.

The reversible blades are the detail we appreciate most. Flip them and you get a fresh cutting surface instead of buying a replacement, which is the same arrangement as the standard model and the reason these handles outlast the abrasive by a wide margin.

For a kitchen with one good serrated knife and a set of 15-degree paring knives, this covers both and takes up about the space of a pen. If your knives are ordinary Western steel, the full-size AccuSharp is the better buy: more handle, the correct angle, about the same money.
