FAQs: Folding Utility Knives

Why do you need a utility knife?

A utility knife is a versatile, multi-tasking knife that can be used for small tasks such as cutting boards, clamshells, slicing shallots, cutting herbs, and cleaning and cutting vegetables. A slightly longer blade is useful when you don’t need the weight of a chef’s knife but, a too-small paring knife can be too uncomfortable.

What should I look for in a utility knife?

A utility knife must have a suitable handle to suit your task and work style.

What is a folding utility knife used for?

Utility knives are lightweight and easy to use. They are often used for cutting tape, cord, strapping, card, or other packaging material.

Buyer's Guide: Folding Utility Knives

Detailed Guide To Choosing The Best Folding Utility Knives

A utility knife, or folding utility knife, is one of the most useful tools for DIYers. It can be used for many purposes, including opening carton boxes, cutting vegetables, and stripping wires. In addition, you can easily fold the knife and keep it in your pocket.

It's hard to beat the ease of being able to access a sizeable folding utility knife at any time. Finding a good knife is easy, but getting the right one for the job can be challenging. The search for the right knife can be overwhelming with so many choices.

You may need to search for the right tool several times before you find it. And we understand that time is precious. So, we did all the legwork for you to help make informed decisions.

Here are the lists of things you need to consider:

Pick Your Steel Wisely

There are many types of steel. The most popular material for the blade is stainless steel. It is durable, rust-resistant, and corrosion-resistant. The blade can also be made from titanium and aluminum.

It's nice to have the stainless variety for a folding utility knife because it requires little maintenance. However, it is more difficult to sharpen than high carbon but has better corrosion resistance.

Avoid knives that list their blade material as "surgical" steel. It is a confusing and meaningless term that sounds fancy.

Knife Handles

Knife handles are important because they determine the blade's efficiency and provide safety during operating.

These are some of the materials used to make standard utility knife handles:

  • Handles that are made of metal or fiberglass are the strongest and most reliable.
  • Plastic handle knives can be found at a low price but are the least sturdy.

The second most important factor is the shape of your utility knife handle. For a more secure grip, curved handles are a common choice. They protect your hand from sliding onto the blade and provide a better grip.

Shape of the Blade 

There are many options for knife blades. Avoid anything that looks too Klingon-like and opt for the drop-point knife shape. It's versatile and easy to use.

You'll find many grinds as you go down the knife rabbit hole. (Grind pertains to the shape of the blade when viewed from the front.) Full flat grinds are the best for everyday carry. It means that the knife is just a wedge from edge to tip. This configuration maximizes a knife's width.

Blade Size

There are many lengths of pocket knives. Some are 7.5 inches long, while others are as short as 2 inches. The task you are assigned will dictate the size of your blade. A large blade is required for heavy tasks like chopping wood. For less complex tasks, smaller and lighter blades will be more suitable.

Size and weight 

It is something that many utility knife guides overlook. Utility knives are small and portable so that they can be carried anywhere with no hassle. It is preferable to use smaller knives than larger ones. Be careful about the knife's weight. Knives that are lighter will break more often. A heavy knife can cause discomfort, so it's not a good idea. You need to find stability in between these two ends.

One-Handed Open 

One-handed folding knives are easier to use and more convenient. One hand is better because you already have the item to be cut and are holding it before you can remove your knife. Utility knives that can be folded and unfolded with one hand often have a spring-loaded push button or sliding button.

Mechanism for Quick-Change

You should be able to easily remove old or dull blades from your pocket knife and replace them with newer ones. Many knives will have a button that allows you to release the blades when pressed. This will allow you to insert the new blade. Before you use the blade, make sure it is securely secured. It is also important to place the eject button in a convenient location so that you don't accidentally press it and pop the blade out while working.


Each manufacturer has its own take on the locking mechanism. They'll claim it is the strongest, fastest, or most efficient. Each has its advantages and disadvantages. You should choose the simplest design possible. Frame locks are the best locking mechanism. Frame locks prevent the blade from collapsing by folding a portion of its frame inward. A good knife will have a frame lock.

Additional information that you should consider when buying a utility knife?

When purchasing a utility knife, there are some other factors you need to consider. Comfortable grips are essential because the knife must be appropriately held while being used. Non-slip ergonomic handles are recommended because they reduce the risk of injuries and allow you to grip the knife comfortably.

It would be great to look for additional features in your knife, like gut hook and wire stripper are nice-to-haves. Additionally, the hand hole because many people need a utility knife on an almost daily basis. Hang hole type of feature is a great option. This feature allows you to hang your essentials from a belt loop or similar accessory.

Consider your budget and personal preferences when deciding how much money you will spend on your folding utility knives. You should always consider the quality before price. Low-quality pocket knives are often of poor quality, and they won't last very long. Also, high quality doesn't always mean expensive. Make sure you choose a high-quality folding pocket knife within your budget.

Ultimately, the folding knife you choose should suit your needs and preferences. You want a knife that is easy to use, durable and cuts well. The best folding knife for you may not work for another person. Likewise, you may not know the best knife for you until you try it.
