How to Dispose of Kitchen Knives

Have you ever experienced the frustration of trying to slice through a tomato with a dull, flimsy knife? Or perhaps you've found yourself struggling to chop through tough cuts of meat with a worn-out blade?

Properly disposing of old, damaged, or unused kitchen knives is often overlooked in the quest for culinary excellence. Many of us are guilty of holding worn-out knives, unaware of their potential hazards. The consequences of neglecting to dispose of kitchen knives responsibly can lead to accidental cuts and injuries to compromised food preparation.

Alternative Options to Throwing Away Your Kitchen Knives

Before we discuss how to dispose of kitchen knives correctly, there are some alternative options you can consider. Here are two popular ones:

Recycle Your Unwanted Knives

Recycling your old kitchen knives is possible if you know what type of metal is used in the blade. If unsure, a magnet test will provide you with the answer. Magnets are attracted to ferrous metals, such as stainless steel, but not to non-ferrous metals.

Scrap metal recyclers are located in most cities and towns. You can find a scrap metal recycler near you by searching online or calling your local recycling center. Some scrap metal recyclers usually accept kitchen knives, but it is always best to call ahead to verify their policies.

Donate Your Old Knives

If your knife collection has become dull, consider donating it. One place to donate your unwanted kitchen knives is to a friend or young adult moving out independently and setting up their first kitchen.

This way, they can upgrade their knife collection as they can afford to. This saves them from having to pay for a brand-new knife set while they have other moving expenses to cover.

Another option is to donate your unwanted knives to an organization like a soup kitchen. You can also donate it to charity organizations like:


Goodwill is a nonprofit organization that helps individuals with barriers to employment. Donating old knives to Goodwill can support its mission by providing resources for job training programs and employment assistance for those in need.

Habitat for Humanity

Habitat for Humanity is a nonprofit organization focused on building and improving homes for those in need. Donating old knives to Habitat for Humanity can help outfit new homes. They can also be sold in their ReStores to raise funds for housing projects.

Salvation Army

The Salvation Army is a global organization offering various social services, including disaster relief, rehabilitation centers, and anti-human trafficking efforts. Donating old knives to the Salvation Army can support their programs and services for needy communities.


GreenDrop is a donation program that supports the American Red Cross, the National Federation of the Blind, and the Military Order of the Purple Heart. Donating old knives to GreenDrop can generate funds to assist these organizations in their humanitarian efforts.

Factors to Consider Before Donating Old Knives

Before you start handing out your unwanted kitchen knives, it's essential to note that not every knife should be donated. There are a few factors to consider when deciding whether to donate a kitchen knife.

First, you should inspect the blade for any chips or cracks. If the blade is damaged, it is not safe to donate.

Second, you should check the handle for any loose or broken parts. A damaged handle can make the knife unsafe to use.

Third, you should consider the knife's overall condition. If it has rust, it may not be worth donating. If you donate a knife, clean it thoroughly before you do so.

How to Dispose of Kitchen Knives Correctly and Safely

If you've looked through your knife collection and determined which you can donate, you may have some that are too badly damaged to donate. You'll need to know how to dispose of these kitchen knives correctly.

What You'll Need

You'll need to gather some things to dispose of your unwanted knife collection. Gather the following:

  • Newspaper
  • Cardboard
  • Heavy duty tape
  • A sturdy box
  • Packaging tape
  • A Sharpie or other marker

What to Do:

There's a special method for disposing of old knives. Here are the four essential steps:

Step 1: Wrap the Knives

Wrap each old, damaged knife in several layers of newspaper to create a protective barrier. This helps prevent accidental cuts during handling and transportation at the disposal site.

Step 2: Prepare the Cardboard

Find a piece of cardboard that is more than twice the depth of the blade. This ensures complete coverage of the blade to prevent any accidental contact.

Fold the cardboard in half to create a protective sleeve for the blade. The folded cardboard will provide a sturdy, safe covering for the blade during disposal.

Step 3: Secure the Knife

Place the back of the blade against the folded side of the cardboard. This positioning prevents the sharp edge from being exposed and ensures safe handling during the next steps.

Use heavy-duty tape to secure the cardboard around the blade. Make sure the tape is tightly wrapped to prevent any movement of the blade within the protective sleeve.

Step 4: Packaging for Knife Disposal in the Trash

Place the wrapped and secured knife in a sturdy box. The box should be able to fully contain the knife and prevent any protrusion of the blade during transport.

Seal the box lid with tape to ensure the knives remain securely enclosed until they are ready for disposal. Clearly label the box as containing sharp objects to alert others to exercise caution when handling the package. This labeling helps prevent accidental injuries.

How to Keep Your Knife Collection Sharp to Avoid Disposal

Of course, if you're not keen on buying new knives or disposing of your current ones, you can always freshen them up. You can do this by sharpening them yourself or taking them to get professionally sharpened.

If you want to sharpen them yourself, you must gather materials. Collect a whetstone (preferably with two grit sides, coarse and fine) and a damp cloth. Place the whetstone on a stable surface with the coarse side facing up.

  • Pro Tip: A damp cloth underneath the whetstone is an easy way to keep it from slipping around during use.

How to Use a Whetstone for Knife Sharpening

Once you've gathered the necessary equipment and have your knife ready, it's time to begin. Here's a step-by-step guide on how to sharpen dull knives.

Step 1: Prepare the Whetstone

Moisten the whetstone with water and let it soak for 10-15 minutes (the time will vary depending on the type of whetstone). This will ensure that the surface is adequately lubricated for sharpening. If you don't have time to soak it, you can also rub the top of the stone with olive oil.

Step 2: Position the Knife

Hold the knife firmly with your dominant hand and place the blade against the whetstone at a 20-degree angle. Use your other hand to maintain the angle and apply gentle pressure.

Step 3: Sharpen With Coarse Grit

Starting from the base of the blade, move the knife across the whetstone in a sweeping motion, maintaining a 20-degree angle. Repeat this motion on both sides of the blade to ensure even sharpening. You can also use a circular motion.

Step 4: Check Sharpness

After several passes on each side, run your finger lightly along the edge to feel for any rough or dull spots. If needed, continue sharpening until the blade feels uniformly sharp.

Step 5: Switch to Fine Grit

Once the blade is adequately sharp, flip the whetstone to use the fine grit side. Repeat the same sweeping motion on both sides of the blade to refine and polish the edge.

Step 6: Test the Knife

After sharpening, carefully wipe the blade with a damp cloth to remove any residue. Test the sharpness by slicing through a piece of paper or gently cutting a ripe tomato. If the knife cuts cleanly and effortlessly, it's successfully sharpened.

How to Maintain Your Sharpened Knives

Regularly sharpen the knife with the whetstone as needed to maintain its sharpness. Proper storage and care will also extend the blade's sharpness.

Well-maintained knives are safer as they require less force to cut through food. This can reduce the risk of slips and accidents. Additionally, sharp knives make food preparation more efficient because they cut properly the first time.

Finally, maintaining sharp knives helps preserve food's texture and appearance. Clean cuts minimize cellular damage and prevent food from looking bruised or discolored.
