When buying a utility knife, there are key features to consider. You’re going to use it on a daily basis for different cuttings, so you should think about these when looking to make a purchase.
Types of Utility Knives
You can categorize utility knives according to their usage and types of cutting they can do. First of all, you can use them for small, quick jobs around the house.
Secondly, when doing various DIY jobs, you’ll probably need a box knife. Finally, professionals use them when cutting cardboard boxes, linoleum, drywall, vinyl flooring, etc.
Types of Material
Utility knives can be made of different materials or even a combination of materials. They can be made of stainless steel, aluminum, plastic, wood, or zinc alloy.
The cheapest ones are those made of plastic, which aren’t long-lasting. The most common material for utility knives is stainless steel for its durability. Furthermore, wood is often used for handles as it prevents slippage.
Utility knives can be categorized by their blades. These can be fixed, retractable, or breakaway. The way blades are attached to the handle will also determine if you can use them for basic cutting, DIY projects, or professional jobs.
With fixed utility knives, the blade is always exposed. In turn, your chances of getting hurt are greater.
The blade is in the secured position, and you can’t adjust it. However, it’s also tightly attached, so it won’t wobble. For that reason, people often use these knives for precise cutting, to cut linoleum, or in DIY projects.
Retractable utility knives are among the most popular for regular, everyday usage. They usually have a button that you can press to expose or retract the blade.
With some, you can choose the length of the blade you need for finer cutting. Therefore, they’re safe, if the sliding mechanism can be a bit wobbly in some models.
Finally, breakaway utility knives have snap-off blades, meaning you don’t have to change the blades when they become dull.
Simply cut them with pliers, and you’ll have a new and fresh blade. People usually use these knives for opening boxes, cutting through insulation, etc.
Many utility knives have blade storage inside them. You don’t have to go and get new blades in the middle of a work task.
You can just get them from the storage and swap them within a couple of seconds. This makes working a lot easier and efficient.
The storage can usually house up to five extra blades, but this varies. You can open it by pressing the button on the utility knife or using a screwdriver to unscrew it.
The comfort of the utility knife depends a lot on the handle. You need something that will feel comfortable in your hands.
Moreover, the handle needs to provide a secure grip to prevent the knife from slipping from your hand in the middle of a cut.
Nowadays, many utility knives have ergonomic handles, cushioned for your comfort. It allows you to work more productively for a longer time, without getting injured.
What is a Utility Knife Used for?
Utility knives or box cutters are tools that are a part of every toolbox. They’re used by professionals and DIY enthusiasts alike.
People use these knives on construction sites, as well as in their homes. You can utilize them for a variety of things, from cutting paper, cartons, opening up packages, to stripping wires, and cutting drywall.
How Do You Use a Utility Knife Safely?
Utility knives are one of the most used tools around. Although they’re generally safe, accidents can happen.
Therefore, it’s always advisable you wear gloves and safety glasses to protect yourself. This way, if anything happens, both your hands and eyes will be protected if slippages happen or the blades start flying around.
First of all, before using the utility knife, you should always inspect it to see if there is any visible damage.
If the blades are dull or rusted, be sure to change them for sharp ones before you start using them.
Be aware that the blades of your utility knife are sharp enough to do the cutting, but also to injure you.
For that reason, always retract the blade when you finish using it. Also, don’t give the knife to someone else if it isn’t retracted. This can cause accidental injuries.
Make sure the knife is used for its intended purpose. Don’t use it to unfasten screws or to loosen up other objects.
When you start cutting, make sure you keep your body and hand out of the cutting line. Also, start cutting away from your body. That way, if your hand slips, you won’t injure your body.
Finally, when disposing of the old blades, make sure you put them in duct tape and then throw them in the bin.
How Do You Sharpen Utility Knife Blades?
Using sharp knife blades is crucial when doing any job. If you use dull blades, you won’t be able to cut anything properly, and you could also hurt yourself.
To sharpen the blades, you need to use the right tools. One method is to use a sharpening stone, which has a coarse side and a fine side.
- First, you should put the stone on a chopping board, with the fine side facing down.
- Hold the knife at an angle of around 20 degrees and start sharpening the blades.
- Use the long directions to sharpen them.
- Now flip the stone and repeat the steps.
Another way to sharpen the blades is by using a sharpening steel. You should hold it vertical and away from your body.
The handle should be on top. Just like with the sharpening stone, your angle should be around 20 degrees. Sharpen the blades in long, steady motions.
How Often Should I Change My Utility Knife Blades?
The blades of your utility knife should always be sharp, to help you work more efficiently and safely. If they start rusting, which can happen quite often, this is a sign you should change them. When your blades become dull, you should get rid of them and load the new ones.
Finally, if you have any problems retracting the blades, they may be jammed. If that’s the case, it’s better to replace them.
Can I Use a Utility Knife to Cut Carpet?
In short – yes. You should make sure your blades are sharp before cutting, though. Here’s how you can cut the carpet:
- Make a small hole in your carpet.
- Pull it up with one hand.
- Use the utility knife in your other hand to cut the raised rug.
