Through repeated use, knife blades become dull and more dangerous than sharp knives. For many people, the most convenient answer is calling on the best electric knife sharpener they can find.
With a dull knife, you have to use more force. The blade may slide off whatever you’re cutting and stab you.

Chef’s Choice 15 XV Trizor Professional Electric Knife Sharpener by EdgeSelect combines strong and durable Trizor design with 15ºXV technology. Its flexible spring guides control the sharpening angle to convert traditional 20º factory edges of household knives into Trizor XV 15º edges.
Chef’s Choice 15 XV Trizor Professional Electric Knife Sharpener by EdgeSelect has three slots or stages. Stage one uses conical disks with diamond abrasives to create ‘micro-grooves’ on both sides as well as a 15º bevel.

Stage three’s flexible abrasive stropping disk system creates a smooth ultra-sharp edge and a third smaller bevel.

Find some dull knives?
Don’t worry!
If your knives need sharpening, consider an electric knife sharpener.
They’re surprisingly easy to use and your knives will be in super sharp in no time.
Your knife may say dishwasher safe on it, but that doesn’t mean it’s always recommended. In fact, the professional chefs we talked to and researched told us putting your knives in the dishwasher will deteriorate them much quicker.
Different kinds of surfaces can break down and damage your knife more quickly than others. That means you’ll need to spend more time sharpening your knives if you’re using the wrong cutting board. The best cutting boards are made from wood or bamboo, plastic, or a wood/plastic composite. Avoid using glass, stone, and steel.
It’s tempting to just toss your knives in the drawer with the rest of your flatware, but all that jostling around can make them more dull quicker. Instead, find a designated knife stand or magnetic strip to store your knives in.
Still need help figuring things out?

Wash food and debris from the knife before inserting into the slots. Follow the manufacturer’s cleaning instructions.
