This knife sharpener from AccuSharp has a few standout features that make it a smart and inexpensive investment. To use the gadget, you place the knife, sharp side up, on a stable surface and run the sharpener along the blade. This method allows it to sharpen any style of knife, including a serrated bread knife, which is typically tricky to work with.

The sharpener features a v-shaped tungsten carbide blade — a super sharp piece of steel common in sharpeners — that will hone your knife in just ten seconds flat, and the inner blade can be swapped out for a new one when needed. While sharpening knives can be intimidating, this tool has an ergonomic grip for stability and comfort, and the handle also has a full-length guard to protect your fingers from the knife’s edge.

Shoppers gave the tool perfect five-star reviews for its ease of use and effectiveness. One customer said that, compared to other sharpeners they’ve used in the past, this version gave their knives surgical sharpness, adding that it’s great for their everyday kitchen knives. Another shopper who has been using the sharpener for more than 15 years said it puts a very sharp edge on their knives and likes that it is safe to use.

At just $11, the sharpener is an inexpensive way to maintain knives at a range of price points, including more expensive blades. Shop the best-seller at Walmart, and keep scrolling for more essential kitchen tools for prepping food.
