The Best Method For Sharpening Dull Ceramic Knives

There is something super satisfying about a perfectly sharpened kitchen knife, especially a ceramic one. It slices so smoothly that you'll actually want to meal prep. Ceramic knives tend to stay sharper for longer thanks to the durable material. However, they aren't immune to wear and tear. While there are tricks to sharpen your dull kitchen knives with a coffee mug or foil, those work better for metal blades. To sharpen your tough ceramic knife, you need a material harder than the blade, and that means diamond. With a mechanical or electric diamond knife sharpener, you can bring your ceramic knives back to new from the comfort of your home.

Diamonds are the hardest naturally occurring material on Earth and the best method for sharpening dull ceramic knives at home. There are many dangers of not using the proper tools to sharpen your knife, including harm to you and the kitchen tool, so you don't want to use any equipment that's not specifically designed for ceramic. While there are services that will refine your knives for you, doing the job yourself can be more convenient and economical. There is a learning curve with sharpening these knives, as the process takes precision, but with a little patience, you'll be back to fine slicing in no time.

Dull blades and minor nicks on your ceramic knife can be fixed with a manual whetstone like SHARPAL's Diamond Sharpening Stone. First, steady your diamond stone on a flat surface. Some products have built-in non-slip guards, but if yours doesn't, use a cutting board covered with a kitchen towel to prevent the block from sliding. Next, angle the knife at 20 degrees. Use one hand to grip the knife's handle and the other to steady the top of the blade. Then, slide the blade's edge across the diamond grit from the bottom of the knife to the tip. Be careful to only apply gentle pressure and do so evenly on both sides of the blade roughly six times. After, test the blade's sharpness and repeat the process if necessary.

To make this task easier, you can use an electric sharpener, like Secura's Electric Knife Sharpener, to file, hone, and polish your ceramic knife with a few swipes through the machine. Just slide your knife from heel to tip through the designated slots and the automatic sharpener will do the work for you. After each swipe, test the blade's sharpness until it reaches your desired refinement. An electrical sharpener can get the job done faster and easier, but it only works for your knives, while a manual sharpening stone also files other tools like scissors, axes, and chisels. So when you're ready to sharpen or hone your kitchen knives, you'll have an edge on the task.
