How To Dispose Of Kitchen Knives

By Herbert Dorman

Kitchen knives are important tools in our kitchens. We use them daily in the hope that they will serve us for a long time before going blunt or needing replacement. A new knife or rather one that is well maintained makes slicing work an extremely easy task. It is vital to know how to dispose of kitchen knives once they become obsolete to avoid any dangers because knives are objects that you cannot just do away with anyhow.

Usually knives may either get blunt, develop rust or even bend a little bit. At this point you may not be sure of what to do with them. You may want to buy another knife, which means you are incurring extra costs, or you may decide to do some repairs or even thoroughly clean it. Moreover, sharpening it is also an option that you may want to consider. But what if the knife is damaged beyond repair? What will you do? The easy option is to throw it away. How safe is that? The answer lies somewhere in this article.


Types Of Kitchen Knives

There are different types of kitchen knives available in the market. You may have interacted with them, but you have no idea what their purpose is. Below are some of them.

Types Of Kitchen Knives

  • Chef’s Knife

This is the most common type of knife in the kitchen. Its blade is long and broad whereas it features a straight edge. It can easily rock back and forth against a chopping board thus making chopping of vegetables and meat amazingly easy. Its design allows it to withstand pressure and is therefore suitable for slicing hard foodstuff.

  • Bread Knife

A bread knife features an edge that is sharply serrated thereby looking like a saw. Alongside this, it has a long blade. If you plan on cutting stuff that are softer like bread, cakes and other types of pastry, then this is the most appropriate knife to use. It cuts them smoothly without distorting their shape.

  • Carving knife

Also known as the slicing knife, it is among the longest in the kitchen. It boasts of a narrow width and is sharp towards the edge. Also, it is slim allowing it to cut meat with much precision. You can use it to slice any type of meat and fruits and vegetables that are large such as watermelons.

  • Butcher Knife

You will most likely find this type of knife in butcheries. It is also known as a cleaver. Its blade is rectangular in shape and has a flat surface. Moreover, it is heavy and can be used to chop raw meat with ease. Besides this, it can also help to crush ginger or garlic when using a chopping board.

  • Steak Knife

They are also referred to as table knives. If you have cooked steak or chicken at the table ready to have lunch or dinner, then the steak knife comes in handy to chop them into your desired pieces. Their edges can either be serrated, semi serrated or not serrated at all. This leaves you with a wide variety of options.


Methods Of Kitchen Knife Disposal

The first step to disposing of your kitchen knife is for you to really decide if you are done using it completely or if it really needs disposing. If your knife is only blunt, then you may not need to rush to get rid of it. What you need to do is sharpen it on your own using a knife sharpener or get a professional to do it for you. This is just but an example. For as long as your knife can be salvaged, do not abandon it entirely. 


Re-selling and Recycling

Old knives can be sold to dealers of scrap metal. These dealers can then convert it into something valuable once again. The money you get from re-selling your knife can be invested in a new knife thereafter. A more environmentally friendly method is to take your knife to the nearest recycling plant, and it will be melted and recycled. But first find out the material of your knife before taking it for recycling. 



Yes, you can donate old knives to secondhand shops or charity homes. But first check to ensure that they are not very blunt or are not entirely covered in rust. It is good to donate something that the next user will find useful. So, you can clean off the rust and even sharpen the knife in case you own a knife sharpener.


Throw them out

This should be the last of your options. Throwing them out does not mean careless disposal in your dustbin. Remember that knives are sharp objects and they can easily harm you. There are ways that you can apply before throwing them out.

  • You can wrap the blade of your knife with a newspaper, let us say 4-5 sheets, and make sure that it is completely covered. Only the handle should be visible. This is the cheapest method because newspapers are easily available.
  • The second method is covering your blade with a bubble wrap in the place of newspaper. This is safer than the newspaper.
  • If you have a cardboard, then this is the safest among the others. Pick a cardboard that is longer than your knife. Fold it so that the knife’s blade can easily fit inside it. You can then use a tape to secure the contents in the cardboard.
  • In a situation where you have no newspapers, cardboard or bubble wraps, you can opt to use cloth pieces to cover the blade of your knife. But this is usually not a safe option as clothes may easily unfold unless you find a way of tightly securing the clothes around your knife. You can also indicate that the clothes have a knife inside so that whoever is curious and unwraps them will not get hurt.


Final Verdict

Kitchen knives do have a limited life span. It reaches a time where you need to get rid of them. Using the right disposal method is important as it will ensure safety and keep the environment clean altogether. Whether it is a chef’s knife or a peeling knife, you need not throw them away carelessly. These are better ways of how to dispose of kitchen knives.
