This Under-$15 Knife Sharpener Has 25K+ 5-Star Reviews

There’s a special kind of cooking frustration that comes from wrestling with a dull knife while trying to slice something delicate like a tomato, only to end up with a mangled mess instead of clean cuts. And while we all know we should sharpen our knives regularly, the reality is that most of us don’t. Traditional sharpening can feel intimidating and time-consuming, or in my case, requires a steady hand I just don’t have after three cups of coffee.

The AnySharp Editions Hands-Free Knife Sharpener solves this problem, thanks to one simple design feature: a powerful suction cup that keeps it firmly planted on any smooth surface while you pull your blade through. Best of all, it’s under $15, comes in a handful of stylish colors (the cream option is particularly chic), and has racked up more than 25,000 five-star reviews on Amazon.

AnySharp Editions Hands-Free Knife Sharpener

The AnySharp sharpener’s suction cup base adheres to countertops, cutting boards, or even your sink with a grip that keeps the unit completely stable during use. You don’t have to worry about holding the sharpener steady (or your knife). With the AnySharp, you can focus on the actual sharpening with a simple pull-through action that takes three to five swipes per knife. 

Whether you’re reviving a cheap paring knife or maintaining your favorite chef’s knife, the AnySharp can handle both serrated and straight-edge blades. The sharpening mechanism uses tungsten carbide blades at a precise angle to efficiently restore your knife’s edge. As someone with a tiny kitchen, I also love that the compact 2.75-inch design won’t hog drawer space, and at just a few ounces, it’s light enough to toss in a camping bag or take to a vacation rental.

One five-star reviewer shared that they were amazed at how well it works, saying, “Holy cow, this thing will put an amazing edge on even the cheapest, $1 knife from the dollar store. It even sharpened scissors and a serrated blade to perfection.” Another shopper praised its hands-free aspect and the firm grip of the suction cup. “When I received this, I must have sharpened everything I had in my kitchen, from knives to scissors! This sharpener suction cups well to the counter, and it’s not big nor bulky.” One even praised it as better than electric: ”Cheapest way to keep your knives sharp! Forget about the electric ones…they break or under perform and replacement or repair is costly.” 

While the AnySharp clearly excels at quick tune-ups, knives with severely damaged edges may need professional attention first. Avoid over-sharpening, too, as the tungsten carbide blades remove a small amount of metal with each use. And while the suction cup works beautifully on smooth surfaces like granite or glass, it won’t grip as well on textured countertops.

Still, for under $15, the AnySharp is a nifty gadget for home cooks who want sharp knives without the hassle or learning curve of traditional sharpening methods. Whether you’re tired of sawing through vegetables with a blade that couldn’t cut butter or you simply want to maintain your knives properly without investing in expensive equipment, this knife sharpener delivers professional results at a bargain price. We can confidently say it’s one of those rare kitchen tools that actually lives up to the hype.
