What To Do With Old Kitchen Knives

A kitchen knife is a tool, and as with all other tools, they eventually wear out and can no longer perform as well as they used to in the kitchen.

It is important to realize when it is time to dispose of a knife before it becomes dangerous to use in the kitchen, where it could cause injury.

A knife should be disposed of when the following conditions are true.

• The knife handle is damaged. If the knife handle is damaged and cannot be replaced, the knife may be unsafe to use and should be disposed of.
• The blade is damaged. A badly cracked, chipped, or worn blade is an indication that it is time to replace your knife.
• The knife blade is worn. If the knife blade has worn down to the point that it can no longer be sharpened properly, it is time to dispose of the knife.

Other reasons to dispose of a knife may include upgrading to newer, better knives or simply having too many knives and needing to scale down your collection. This can leave you in possession of older or unwanted knives that are still in useable condition.

A knife that doesn’t work well in the kitchen is still a dangerous object and should be disposed of responsibly.

There are a few options for disposing of old kitchen knives. If the knife is still in good condition, you can donate it to a local thrift store or shelter.

If the knife is not in good condition, you can recycle it at a metal recycling center. If you want to dispose of the knife yourself, you can do so by wrapping it in a heavy-duty garbage bag and placing it in the trash.

How To Dispose Of Kitchen Knives (Properly & Safely)

If you’re like most people, you probably have a few kitchen knives that you never use and are just taking up space in your drawer. 

Getting rid of them can be tricky, as you don’t want to end up hurting yourself or someone else. 

Here are some safe and effective tips for disposing of kitchen knives responsibly.

1. Donate Or Give Away The Old Knife.

If the knife is still in good condition, you could give it to a family member who could use it or consider donating it to a local shelter or food bank. They can put it to good use when preparing food for people in need.

If you no longer need or want the knife and there is no damage to it, giving it away to someone who can use it is a good option. However, you should never donate or give away a damaged knife that could cause injury.

2. Sell Your Old Knives

If your old kitchen knives are still in good or useable condition, you could consider selling your old knives. This option will allow you to get some cash value from your old knives that you can put towards purchasing new, upgraded knives.

Good places to sell your knives are thrift shops, pawn shops, or local online marketplaces on social media platforms.

Once again, selling your old knives is only an option if the knives are still in useable condition and will not pose a danger to the user.

3. Recycle Your Old Kitchen Knives

Recycling is important to preserving natural resources and helping protect our planet, but can you recycle old knives?

The possibility of recycling old kitchen knives will largely depend on the recycling facilities available in your area. In some places, this is a viable option with conditions on how the knives are delivered to the recycling center, but knives are not accepted for recycling in other locations.

We will detail the recycling of kitchen knives, what you need to investigate, and how to recycle the knives in a dedicated section below. 

4. Recondition Your Old Kitchen Knives

Some knives, especially larger knives, can be reconditioned or transformed to give new life to the knife.

Custom knife makers may be able to convert a damaged large knife into a smaller knife by removing the damaged sections of the blade and replacing the handle material in the knife.

This method allows you to re-purpose old knives and continue using them in the kitchen, but it may only be a viable option for expensive knives. Reconditioning a cheap knife can be more expensive than buying a new one!

5. Throw Your Old Kitchen Knives In The Trash 

The final option for disposing of your old kitchen knives, especially if they are in poor condition, is to throw them in the trash. This option requires that you take special care in disposing of the knives to prevent injury to anyone who will handle the trash.

Disposing of a knife in the trash requires some preparation of the knife for disposal, which we will detail in this article a little later.

If you’re still unsure about disposing of a knife in the trash, your best bet is to contact your local waste management company for guidance. They can help you find the best way to dispose of it safely and responsibly.

Can You Throw Out Kitchen Knives?

Once you’ve determined that your knives are ready for retirement, it’s time to think about how you’re going to dispose of them. 

The safest way to do this is to cover the sharp edge and point of the knife by securely covering the blade in robust materials that can prevent the blade from harming someone. Then, package the knife properly before throwing it in the trash.

We recommend taking the following steps to dispose of a knife in the trash.

1. Wrap the blade in the newspaper. Wrap the blade in several layers of newspaper, which will help to prevent the sharp edge from cutting through the rest of the packaging. Fold the end of the newspaper over the knife’s point several times to create a thicker layer of paper, preventing the point from stabbing through the paper. A piece of cork on the knife’s point is also a good means of rendering the knife’s point safe. An old cloth can be used as an alternative to the newspaper.
2. Secure the newspaper in place. Secure the newspaper of cloth in place over the knife blade with elastic bands.
3. Wrap the entire cardboard. Wrap the entire knife in flexible, durable, corrugated cardboard. You can easily tear up an old cardboard box for this purpose. The cardboard acts as an additional layer of protection should the knife cut or pierce the newspaper. 
4. Tape up the cardboard. Use packing tape to secure the cardboard around the knife and ensure it will not come loose or that the knife will slip out of the packaging.
5. Mark the knife packaging. Write a warning such as “Sharp” or “Knife” on the outside of the package in a permanent marker to warn refuse workers that they are dealing with a sharp object.
6. Place the knife in a sturdy container. Finally, place the knife or knives in a sturdy container, such as a stiff cardboard box or an old coffee can, and seal the lid with tape.
7. Throw the knife in the trash. With the knife packaged in this way, it can be safely disposed of in your normal trash and will not harm children, pets, or refuse workers.

TIP: Transporting knives requires some planning, which involves the safety of the packer, the transporter, the unpacker, and the knife itself! Find out more about packing kitchen knives in the article below:

Where Can I Dispose Of My Old Kitchen Knives?

There may sometimes be a dilemma about where to dispose of old kitchen knives. While you may be able to dispose of old kitchen knives in the trash if they are properly packaged for protection, this method is not necessarily allowed in all locations.

What other methods are available to you, and where can you take your old kitchen knives to get rid of them?

If you are not allowed to dispose of knives in your roadside trash collection, you may have to take other measures to get rid of knives that are damaged beyond repair or re-use.

Some waste management centers will accept knives if you deliver the knives to the waste management center yourself rather than placing the knives in the trash for collection.

Other waste management centers have bins outside earmarked for various types of waste, including sharp metal objects. Some centers will also take them from you by hand if you deliver the knives wrapped as previously described to prevent injury.

Not all waste management centers accept knives, whether delivered or collected, so it is important to enquire beforehand by phoning or emailing your local waste collection service before taking your knives to them for disposal.

If your old kitchen knives are still in reasonable, usable condition, you may consider giving them to a local charity or thrift shop.

Do Charity Shops Take Kitchen Knives?

If you have knives still in useable condition, it makes sense to give them to a person, charity, or thrift shop that may be able to use them or sell them to raise money for the charity or organization.

While this is a noble gesture, some charity shops are restricted by what they are allowed to accept for donations for resale to the public.

Before going down to your local charity shop with your unwanted knives, the best strategy is to call ahead and establish their policy regarding accepting kitchen knives.

Some charity shops will accept knives under a certain size and length, while others do not accept knives of any shape or form.

If your charity shop does not accept your old kitchen knives, consider donating your old knives to a local school where the knives can be put to good use in their cooking classes.

TIP: Proper storing and organizing of your knives will keep them in good condition, keep them sharper for longer, and make them ready to use at any time! Find out more in the article below:

Can You Recycle Steel Knives?

For many people, recycling steel kitchen knives does not come to mind immediately when disposing of old knives.

It is possible to recycle knives in certain instances, but some recycling centers do not have the facility to accept knives.

If your city’s recycling service does not accept kitchen knives, you can always try private recycling companies that may be willing to take the knives off your hands.

One of the best ways to recycle old kitchen knives is to take them down to your local scrap metal dealer. Some scrap metal dealers will even give you a few dollars for your old knives.

Even though it is possible to recycle the steel in the knives, some recycling centers do not accept knives because of the danger involved in sorting and processing them.

TIP: Sharpening your knives is a crucial part of knife maintenance and will affect the usability and longevity of your knives. Check out the comparison of sharpening methods in the article below:

Do Knives Go in Recycle Bin?

If your recycling center accepts knives, they may or may not accept them in recycling bins. Some recycling centers have the means to safely transport sharp objects deposited in the bins, but others do not.

In most cases where knives are accepted in recycling bins, they need to be packaged securely to avoid harm coming to the people who empty the bins on collection day. Always check with your local recycling center to see if they accept knives before placing them in the recycling bin. 

Some centers have strict guidelines about what can be recycled, so it’s always best to check first. If your center does accept knives, make sure to recycle them properly.

Knives should all be deposited in the recycle bin designated to receive these items rather than the regular recycling bins.

The best way to secure the knives before dropping them in the recycling is to wrap and secure the blade in the same way that we discussed for disposing of the knives in the trash.
