I know many people always tend to argue that knives will not always be sharp. This is not always the case. However, there are many ways which will ruin your knives faster than you think. The following are some of the common behaviors which lead to knife dullness:

  • Storing your knives unsheathed in the utensil drawer- Apart from this being dangerous to your life, it makes knives to be dull. Unsheathed knives will always rub against other things. The best way to store a knife to keep it in a knife block and also on a magnetic knife strip.
  • Sliding your knife across the chopping board to clear away what you have actually chopped – This is a common behavior which many people do.

This will prevent your knife from becoming dull faster.
  • Putting knives into dish washers – Knives are not meant to go into dish washers. Dish washers detergents are very abrasive. The banging around which usually happens during the washing process is not good for your sharp knife. It will definitely take the sharp edge off your knife without even noticing.
