A good quality kitchen knife should serve you very well for many years. Once it’s finally bit the dust, however, you’ll need to find ways to get rid of it safely and securely. How can you trash or recycle your once-trusty tool? On this page, we’ll discuss how to dispose of kitchen knives. 

We’ll cover how to recycle a knife, how to throw one away, and how to keep everyone safe when doing so. We’ll also discuss a few things that are worth keeping in mind once your knife starts showing signs of age. 

Things to Consider When Disposing of Kitchen Knives 

Before discussing how to dispose of kitchen knives, it’s worth touching on what you’ll need to keep in mind when getting rid of them. None of this is rocket science, but it can pay to get clued up before accidentally hurting yourself or damaging someone’s property.


Safety should be a top priority when disposing of a kitchen knife. Even an older chef’s knife can still have a surprisingly sharp tip and blade. Any disposal method you use should effectively eliminate the dangers presented by its edge. 

We cover some easy ways to do this further down this page. 

The Environment

When getting rid of your kitchen knives, it’s important to keep the environment in mind. A depressing amount of waste goes to landfills every year, and recycling plants often struggle to keep up with the volume of donations they receive. 

Wherever possible, it’s best to consider the environment when disposing of your chef’s knives. Can you donate your knives? Recycle them effectively? Get another few months’ worths of use out of them? The decision is yours. 

Their Condition – Can They Be Reused?

Sometimes, a knife has simply lost all usefulness. Often, however, it’s possible to extend the life of your knives with a little TLC. Rust can be removed with the right techniques and a few minutes of sharpening can get things back to where they need to be. 

It’s not always possible but is worth considering if you haven’t already.

How to Dispose of Kitchen Knives Safely – Your Options

Check out the options below to learn how to dispose of kitchen knives the right way!  

The Scrap Metal Section of Your Recycling Center 

Many recycling centers will happily take old kitchen knives provided they’re made from the right materials. Depending on the center you choose, you’ll have to know the following: 

  • Which metals your knife is made from 
  • Whether they take the knife whole or with the handle removed
  • How they accept knife donations (packaged VS loose) 
  • What condition your knife has to be in 

If you’re unsure, call your local center and see what they recommend. In most cases, it’s relatively straightforward to recycle your kitchen knives. 

If your knives are still in a reasonable condition, we strongly recommend donating them instead of throwing them away. Donation is even preferable to recycling as it saves energy and immediately gives the knives to someone who needs them.

You could try the following donation ideas: 

  • A friend or relative 
  • A local Goodwill or other charity stores 
  • Your local police department (check what they accept)
