Learn exactly how to Dispose of a Kitchen Knife Safely

After buying a shiny new kitchen knife, the first thing that you’ll probably do is to throw away your old one. Well, some won’t and will only keep it in the kitchen, but let’s face it, why would you even bother using it if you can slice and dice using your brand new, razor-sharp knife, right?

Check out here the best kitchen knives you can buy.

You can dispose of a kitchen knife safely and properly by cleaning it, wrapping it in newspaper or bubble wrap, securing the blade with cardboard, placing everything in a box, and marking that the box has a sharp object in it. Once that’s done, you can donate, recycle, or throw the knife away. 

These options may seem too simple, but there are some things you should consider before you dispose of a kitchen knife. Stick around as we discuss them in great detail, and, possibly, help you avoid sending someone to the emergency room!

How to Dispose of Kitchen Knives

Never toss a knife in the trash without proper protection, or you risk sending someone to the emergency room. Okay, maybe that’s quite a stretch, but disposing of a kitchen knife shouldn’t be at the cost of injuring someone.

So whether you’re donating, recycling, or throwing away your old kitchen knife, you must keep it adequately wrapped and clearly labeled. Here are the materials that you’ll need to dispose of a kitchen knife safely and properly:

  • Newspaper or bubble wrap
  • Piece of cardboard
  • Duct tape or any heavy-duty tape
  • Marker
  • Small cardboard box

This process won’t take longer than 5 minutes, but it’s the safest way to dispose of a kitchen knife. Remember, even if you’re donating your knife to Goodwill, you still have to go through these steps to keep the workers safe whenever they’re handling your donation.

Here are the five steps that you need to do every time you’ll dispose of a kitchen knife:

  1. Wrap the knife with newspaper or bubble wrap to conceal the blade. You can use either or both, but the idea is to keep people safe whenever they’re working near the knife.
  2. Secure the newspaper or bubble wrap with tape. Never use tape directly onto the knife because it increases the risk of injuring someone while trying to take it off.
  3. Use cardboard to secure the blade. Find cardboard with a size that is twice the depth of your knife then fold it in half. Put it against the fold of the cardboard to keep it in place while inside a container.
  4. Secure the cardboard with tape. Make sure that the cardboard tightly fits the knife, then keep it in place with tape.
  5. Use a marker to write the type of knife on the cardboard. Whether you’re donating or throwing away your old knife, it’ll be easier for people to handle it if they know the type of knife they’re holding.
  6. Put the knife in a small cardboard box. Be sure to secure it with tape to keep it safe for sanitation workers at the dump, recyclers at the facility, or volunteers at the donation center.
  7. Donate, recycle, or throw it out. Now that you’ve secured your kitchen knife, it’s time to send it to its destination.

Throwing away your old kitchen knife should be your last resort because, as mentioned, people can use knives for a long time. It can be a bit dull, or you might think it’s unusable, but others can still make good use of it.

How to Donate Your Old Kitchen Knife

Some kitchen knives are so good, you can pass it down to generations, and it will still work as good as new! But let’s not overstretch ourselves here and just say that your old kitchen knife only needs a bit of sharpening. The point is that it may be unusable for your standard, but another kitchen might have a better use for it.

So, consider your kitchen knife’s condition before you think about disposing of it and see if other people can still use it properly. There are several reasons why it is no longer good for your kitchen, but as long as it can cut food, there’ll be someone who would gladly take it.

You can give it to a friend who is trying to set up her first kitchen; you can donate it to local shelters, second-hand stores, and soup kitchens; or send it to a local Goodwill or Salvation Army donation center. Some of them will even offer to pick it up for free!

You can’t just send it to them, though. So always follow these things whenever you donate a kitchen knife:

  • As a sign of courtesy, clean the knife properly before handing it over to your recipient. It’s a donation, that’s true, but you don’t have to make it look like one.
  • Avoid using tape directly onto the knife; instead, wrap it with several layers of newspaper before securing it with tape. Always conceal the blade to minimize the risk of injuring other people.
  • If you’re donating a set of knives, it would be best to label them. It’ll be easier for others to identify the type of knife that they’re handling, further minimizing the risk of injury.
  • Keep it inside a cardboard box, sealed with heavy-duty tape. Whether you’re donating or throwing your knife, keep it sealed in a box for easier and safer disposal.

Sure, you’re only donating, but giving away a clean knife is a sign of courtesy. Plus, let’s try to avoid injuring someone who’s trying to remove the tape from the knife or just working close to it, okay?

How to Recycle Your Old Kitchen Knife

If you really think that your kitchen knife is no longer usable, then recycling it would be your best option. You can’t just toss it in the curbside recycling bin, though. That’s a huge no-no when disposing of a kitchen knife.

What you should do instead, is to try and figure out the material of your knife—is it iron, stainless steel, carbon steel, aluminum, or titanium? After figuring out its composition, put a clear label on it, then find the closest scrap metal recycling facility or, at least, a transfer station for proper disposal.

However, recycling your kitchen knife doesn’t mean that you can just bring all of your old knives to the recycling facility. You still need to keep it wrapped in newspaper and place it in a cardboard box for proper disposal or safe handling.

If you want to make some money from your old knife, you can even have it listed in various online trading sites to see if anyone is interested. It can be someone who is looking for a kitchen knife or a scrap metal dealer. Remember, regardless of how unusable your kitchen knife might be, people will still pay you for it! 


Even when dull—or even if you think your old kitchen knife is useless—it’s still a sharp object that can injure people who are working close to it. That’s why you should never, by any means, toss your old knife directly to the trash. The least that you can do is to use a few layers of newspaper, secured with tape before throwing it out.

Knowing how to safely and properly dispose of a kitchen knife will keep others safe and make it easier for other people to reuse your old knife. You can donate it, recycle, sell for some money, or just throw it away, but be sure that the blade is concealed and safe for handling.
