These bad habits can ruin your kitchen knives

1. Scraping it sideways on the board

Knives are made to cut in only two directions, back and forth and not side to side, so try not to use your good knives in a scraping manner. It may be instinct to move and gather all that chopped food on the board with the blade of the knife but it will damage the edge over time. If you can’t break the habit completely, at least try and do it gently and without much downward force. 

2. Using it on anything other than wood or plastic 

There are boards and blocks made from all sorts of materials but many of them are not knife-friendly. Stone or marble boards and glass surfaces should be reserved for serving food, not preparing it (at least not with a knife) since they will dull your blade faster than almost anything else.

Bamboo and plastic are the softest — and often cheapest — cutting board materials and will be gentle on your blades. Most other types of wood cutting boards, however, have enough give not to damage the blade. 

3. Storing it free in a drawer 

This is probably the biggest mistake folks make with their kitchen knives. I’ve seen it more times than I can count and it hurts every time. Letting your knives clink around in a drawer with other knives and metal tools will dull or chip them over time. It’s understandable to not want a clumsy knife block on the counter, but there are some pretty sleek options these days like this and this

You can also buy in-drawer wooden knife racks or sheath your knives in plastic cases. The coolest option may be to store the knives on one of these magnetic knife racks and show off your shiny blades to dinner guests. Just be gentle when placing knives on and removing them from the magnet so as not to scrape the blade.

4. Letting it sit in the sink or putting it in the dishwasher

For many reasons, your knives should never go in the dishwasher. It’ll likely damage the handles, and the blades should never be exposed to water for that long. Speaking of which, never let a knife sit wet in the sink or anywhere else for that matter. That means no soaking, ever, and when you’ve finished washing it by hand, dry it immediately or the metal will become susceptible to rust and corrosion.

5. Cutting nonfood items or using your knife as a general tool

Good knives may seem like a multipurpose tool but they should only be used for food prep. Try not to cut any nonfood items like plastic, cardboard or other packaging. And don’t even think about employing your knife as a screwdriver or lever to pry open something stuck.

6. Using a metal scrubber or rough sponge to clean it

It shouldn’t come as a surprise that using metal or another rough material to clean your knife blade could lead to big problems. Instead, use hot water and a soft sponge or cloth. Your knives should never be so dirty that those aren’t enough to get them clean. 

7. Oversharpening the blade

There comes a point at which a knife blade can’t be sharpened anymore, and if you continue to pound it on a steel or whetstone, you’ll only be shaving off the blade itself and shortening the knife’s life span. Here’s a guide to sharpening your kitchen knives.
