Utility knives are a very useful tool for many different tasks around the home and garden.
They can be used for opening boxes, stripping wire or cables, cutting drywall and sheetrock, and so much more.
One of the most important things to note about utility knives is that there are multiple styles of blades to choose from. Knowing which blade fits your needs will help you find the perfect knife.
Is there a difference in utility knife blades?
Yes! There’s a huge difference in the function and use of utility knife blades.
In this guide you will learn more about the types of utility knife blades, their composition, their main uses, and other facts about them.
First and foremost, the toughness of a utility blade allows the blade to be used in more rugged environments like construction or industrial settings.
More often than not, utility blades are razor-sharp for their uses. Utility blades that are meant to cut wire or cables will have serrated edges and very sharp edges to cut through tough materials.
The second aspect of utility knife blades is their size and design, which is essential for their use.
Depending on the function you’re looking to perform with your utility knife, you’ll need a small blade that doesn’t take up too much of your hand’s length or handle space.
Material Composition of Utility Knife Blades
Like other tools, different types of utility knife blades need to be made of durable materials that will protect the structural integrity of the blade.
Some utility knife blades are made from coated metals that prevent rusting and corrosion while also helping to keep the blade’s edge more intact.
Other utility blades are made from steel with a coating applied to prevent damage and corrosion.
The common material structure would be carbon steel blade, carbide tipped, stainless steel, titanium alloy, and ceramic.
Types of Utility Knife Blades
Hook blades are available on utility knives that have a blade with a wide hook-shaped tip, which can be used for cutting thick or heavy materials when using the entire knife. There are two primary uses for these knives: cutting linoleum and being used as a carpet knife, and trimming the edge of shingles.
The hooked blade is primarily used in residential applications as well as construction work. The hooked blade is also useful for cutting through metal using an open-type hacksaw.
Hook blades are not designed to cut wood, but they can be used in this capacity with practice. The hook blade can be used in a rotary motion to cut through wood or plastic.
Scalloped Edge Blades
Scalloped edge blades are knives with a scalloped edge that are perfect for cutting a lot of foods like fruits and vegetables. Out of the kitchen, however, scallop blades for utility knives are used for cutting styrofoam insulation to limit the mess and receive a clean, smooth edge as an end result.
Clamps can be attached to either side of the blade so that you can clamp onto both sides at once. They come in various shapes and sizes, and a lot of times they also have specially-designed teeth on them which serve different purposes: such as scraping or scoring.
Serrated Edge Blades
The serrated edge blade cuts through very dense materials in the same way as a scalloped edge blade.
The difference between the two is how they are used. The serrated edge blade is used in a sawing motion, while the scalloped edge blade is best for slicing motions. Serrated edges have rougher edges than their counterparts, which not only provide extra protection for the user but also allow for a safer cutting experience with extremely dense materials that are difficult to cut through.
The length of serrated blades range from 4 inches to 7 inches. In general, anything longer than 7 inches is considered a specialty blade. Serrated edge blades can be found in both wood chisels and in carpet knives. The longer blades are usually used for more industrial tasks such as cutting carpet and vinyl flooring, or they are used for culinary arts when slicing through a variety of foods such as bread.
Pointed Tip Blades
Utility knife blades that have pointed tips are probably the closest thing to a standard utility blade for most people. They are a great option for materials that are harder to initially puncture before continuing the cut such as fabrics, flexible plastics, and drywall.
Pointed Tip Blades are often the go-to variety of blade for most people. They’re perfect for materials such as fabrics, flexible plastic, and drywall where it would be difficult to get an initial puncture before continuing the cut. Tanto Tip Blades Tanto Tip Blades are known for their thick, pronounced blade. This is great for cutting through hard materials like ceramic tile and metal but may be a bit more difficult to use for more flexible materials like fabric. This type of blade is also often referred to as a Chisel Blade because of the look of the tip compared to other blades.
Rounded Tip Blades
Rounded tip utility blades are a relatively new type of blade that has been in the market for about half the time of pointed tip blades. They are much more aggressive than their pointed tip counterparts and therefore more suitable for a variety of materials like wood, paint, and rubber.
They are less common than their pointed tip counterparts but are just as effective. Rounded tip utility knives are great on materials that would be hard to get an initial puncture like wood, rubber, and resin.
Snap Off Blades
Snap Off blades come as one long, sturdy blade which you can extend to cut through thick substances like fiberglass insulation.
These particular Snap-Off blades are designed with multiple seams, allowing you to snap off smaller segments at a time so that each segment will have a sharp edge to cut with, making them last much longer than standard two sided utility knives.
Snap Off blades have a number of different qualities that make them the ideal blade for utility knives. One of the main qualities is their ability to cut through thick insulation with ease, and last much longer than standard utility knife blades.
These blades are also made of stainless steel, making them incredibly durable, another significant quality that makes these blades stand out from the crowd.
The other main quality is their ability to snap off into smaller pieces so that you can use just one piece at a time in order to get a new blade each time your utility knife runs out. This allows you to stay on track with your home project without having to worry about running out of sharp blades while working in your attic or crawl space.
