Whether you’re a professional chef or a home cook who enjoys preparing fresh meals for the family, you’ll need to take proper care of your knives. When kitchen knives are maintained properly, they are able to make quick work of food prep, as well as produce clean cuts on a variety of cooked meats. One essential tool that you’ll want to invest in is a quality knife sharpener. KitchenIQ has a few attractive models that are sure to meet your everyday needs.

If you’re looking for a knife sharpener that is quick and easy to use, go with the KitchenIQ Edge Grip 2-Stage Knife Sharpener. It’s more basic in design, as it doesn’t require any adjustments. You simply run the knife’s blade through the coarse slot to restore dull and damaged blades, or the fine slot to polish the blades. The advantage of going with this model is its patented edge grip feature. This allows the sharpener to be used on the edge of a table or countertop.

Go with the KitchenIQ Diamond Pro Pull-Thru Knife & Scissor Sharpener if you have household scissors you’d like to sharpen in addition to your knives. The patented scissor sharpener with floating ceramic rods sits just below the coarse and fine sharpening slots and is super easy to use. The device has a few added features, such as soft touch handles and a non-slip bottom for stability. It’s even designed to be used by both right- and left-handers. 

If you’re interested in a knife sharpener that allows you to have more control, the KitchenIQ Angle Adjust Manual Knife Sharpener is your best bet. It comes with an angle adjust knob that can be turned to your desired angle. That means you’ll be able to sharpen your knives so that they are restored to their original factory-produced sharpening angles. In addition to the coarse and fine slots that you find on most KitchenIQ sharpeners, this model has a serrated slot for sharpening your favorite serrated knives.
