10 Best Utility Knife Blades of 2021 – Top Picks & Reviews
Few tools are as versatile as a utility knife. Whether you’re just opening boxes or your cutting drywall, utility knives are the go-to tool for many jobs. Unlike a regular knife, you can easily replace the blade of a utility knife in a matter of seconds.
Since the blades are so replaceable, you end up going through them pretty quickly. After going through several hundred blades, we decided to see if there was any difference between brands. To our surprise, the differences were quite blatant.
We’ve narrowed down the vast selection of available blades to 10 popular choices and our three favorites. We’re going to share everything we learned about these blades in the following reviews so that you can make an informed decision about what blades to put in your knife as well.

The 10 Best Utility Knife Blades
1. Goldblatt G08283 Utility Blades – Best Overall
We tested a lot of blades for this list, but out of them all, our favorite set was the Goldblatt G08283 Utility Blades. These blades are crafted from durable SK2M steel, making them longer lasting than other blades we tested. They feature precision double-honed edges that stay sharp for a long time, regardless of what you’re cutting through.
We really liked these blades, but it’s the case that clinched the deal. This dispenser is very easy to use and safe for your fingers. You can remove a single blade or 5 blades at once, allowing for more versatility than any other dispenser we tested. There’s even a blade indicator that makes it easy to tell how many blades are left so you know to order more before you run out.
Because of the high quality of these blades and the included dispenser, this 100-blade pack is more expensive than some of the other options we tested. But for our dime, the increased price is worth it.
2. CRAFTSMAN CMHT11921A Utility Knife Blades – Best Value
In truth, all of the blades we tested are pretty similar with only minor differences separating them. One of the most noticeable differences is the price, and considering how affordable the CRAFTSMAN CMHT11921A blades are, we think they’re the best utility knife blades for the money.
You’ll get 100 blades with a hard-plastic dispenser that makes it easy to remove them individually. Each blade features a precision-honed edge that extends its usable cutting life. Compared to other blades we tested, these seem a bit thicker, making them less likely to snap under pressure.
Most utility blades feature an oil coating to prevent rust and corrosion. These CRAFTSMAN blades do too, but there was too much oil in the case, and it gets on your hands every time you remove a blade. But that’s a minor complaint and our hands are usually dirty when we’re using a utility knife anyway, so it’s something we can easily look past.
3. LENOX Utility Knife Blades – Premium Choice
Most of the blades we tested look pretty much identical. However, the LENOX Utility Knife Blades have a unique appearance that sets them apart. It’s not their looks that make them special though.
The first thing you’ll notice is the bright gold cutting edge of these blades. That’s a high-speed steel edge with a titanium coating that’s meant to keep it sharp for a longer time than other blades, and in our experience, it’s quite effective.
These blades feature bi-metal construction that’s shatter-proof, eliminating the most common type of blade break. You’ll also notice that there are 4 notches on the top of these blades, rather than the standard 2. This lets you mount it deeper or more extended in your knife, providing more versatility in its use.
With all of these great features, it shouldn’t come as much of a surprise that these blades are more expensive than most of the competition. But considering how much longer they last, it feels like a worthwhile tradeoff.
4. Rapid Edge Serrated Utility Knife Blades
Most of the blades we tested featured straight edges, but the Rapid Edge Serrated Utility Knife Blades have a serrated edge instead. This edge gives it improved cutting power and makes it much sharper. In some materials, we found that this edge cuts deeper and easier than a straight-edged blade. But we also noticed that some materials, such as drywall, wore these blades out just as fast as standard blades.
Unfortunately, these blades are about twice the price of similar straight-edge blades. If you’re only cutting cardboard, the improved cutting life might be worth the extra expense. But for cutting drywall and other hard materials, these blades are simply overpriced since they last about the same as regular blades.
There is one thing we really liked about these blades — the tips don’t break very easily. The tips of utility blades usually snap pretty easily, but these are more durable. Still, that’s not quite enough to earn these blades a spot in our top three.
5. WORKPRO SK5 Utility Knife Blades
Altogether, the WORKPRO SK5 Utility Knife Blades are great, but they’re held back by an awful dispenser. At first, the dispenser seems pretty decent. It’s got a plastic slide-out that safely dispenses a single blade so you won’t cut your fingers. But the slide-out got jammed up very quickly and then the dispenser was practically useless.
Aside from the garbage dispenser, these blades were solid. You’ll get 100 in a package that’s priced affordably. They’re made from durable SK5 steel, ensuring they last as long as any blades we’ve tested. They feature a light coating of oil to prevent corrosion, but not so much as to make a mess. If it weren’t for the cheap dispenser failing on us, these blades would have likely ranked much higher on our list.
6. DEWALT Utility Blades
We’ve used a lot of DEWALT tools with great success, but their utility blades aren’t favorites of ours. They’re too expensive for what you get and the blades aren’t the highest quality. The edges are ground unevenly, which doesn’t really affect their use but shows low-quality craftsmanship.
Though we weren’t impressed with these blades, the dispenser is great. It holds all 75 blades that come in a pack and dispenses them safely so you won’t get cut. The blades are heat treated, making them 20% stronger. They also feature induction-hardened cutting edges that are supposed to last 75% longer, though that wasn’t our experience. If they had lasted that long, these would be at the top of the list. Instead, we got a similar lifespan from these blades as we did from all the others we tested. Taking that into account, these feel pretty overpriced, making it seem like you’re mostly just paying for the DEWALT name.
7. Stanley 11-921T Utility Blades
The Stanley 11-921T Utility Blades offer precision-honed edges for consistent cutting life. They don’t last longer than other blades we tested, though we hoped they would, considering their high price. These are quite a bit more expensive than other options, but they don’t offer anything special except for a decent blade dispenser.
The dispenser is small and only holds a few blades, but it’s got a nice slide-out mechanism and it fits easily into your pocket. You won’t accidentally cut yourself with it, and it’s one of our favorite dispensers overall.
But a quality blade dispenser isn’t what we purchased these for. We wanted quality utility blades, and these were just average. You get just 10 blades in a pack for only slightly less money than 100 blades from other manufacturers. That’s just too much of a price difference for us to overlook.
8. IRWIN Tools 2084200 Blue Blade Utility Blade
With just 20 blades in a package that costs as much as 100 blades from other manufacturers, we think you can safely call the IRWIN Tools 2084200 Utility Blades overpriced. For the price, we were hoping to at least get a quality blade dispenser. Unfortunately, the included case is a cheesy joke that we threw away after using it once.
When we pay more for a tool, we generally expect it to be better-built and longer-lasting. But these blades are neither. They offer about the same cutting ability and lifespan as much cheaper alternatives we tested. Since they’re the same quality, we’d rather save our money and get several times as many blades for the price.
9. IVY Classic 11172 Utility Knife Blades
These basic utility knife blades from IVY Classic come with 100 in a package. They’re housed in a hard-plastic dispenser that we could never get to dispense blades easily. We ended up wasting more time wrestling blades from the package than we would have liked.
Despite the low-quality case, these blades are pretty expensive. With this in mind, we expected some superior performance from them. However, they dulled very quickly in our experience. On the bright side, these blades feature an edge that can be resharpened. But even at this high price, who is really going to resharpen their utility knife blades?
10. BAZIC Utility Knife Replacement Blade
For the number of blades you get, the BAZIC Utility Knife Replacement Blades are priced rather reasonably. In total, you’ll get 240 blades, but you won’t get a dispenser for them. Instead, they come in packs of ten that are just housed in a cardboard and plastic wrapping. Careful with your fingers!
At first, these blades seemed fine. They fit in our knives and they cut various materials just like other blades. But we started breaking blades pretty quickly. These tend to snap off with less pressure than other blades.
We were quite surprised when one of these blades slipped out of the knife it was in. This is a strange occurrence that we’ve never encountered before, but it’s likely because of how thin these blades are. They’re noticeably thinner than other blades we tested, which is probably why they break so easily as well.
Blades are blades, right? Well, that’s what we thought before we started testing out so many different blades for this list. After using and abusing utility blades from a wide range of manufacturers, we realized that there are some blatant differences between models.
In reality, pretty much any of these blades will work for most standard jobs you’d need a utility knife for. But that doesn’t mean they all perform the same. Some last longer than others. Certain blades snap easily. There are even blades that didn’t fit our knives right!
To help you avoid any of these issues, we’ve written this short buyer’s guide that should help you determine the differences between blades and assist you in figuring out which blades are the best fit for you.
What Are You Cutting?
The first, and likely most important question to ask yourself is what are you going to cut with these blades? Utility knives are multi-purpose instruments and these blades can cut just about anything. But that doesn’t mean all blades cut all materials the same.
We’ve noticed that some of the premium blades with precision-honed edges and hardened blades last longer when cutting through softer materials such as cardboard and Styrofoam.
But when cutting through harder materials like drywall, all of the blades seemed to be destroyed within a similar amount of time.
So, what does this mean for you?
Basically, if you’re cutting soft materials like cardboard, you can get the premium blades and expect a longer lifespan. But if you’re cutting drywall or other hard materials, you’re probably better off getting the basic blades because they’ll wear out in about the same amount of time.
The next thing to look at is the total quantity of blades included. Some brands sell their blades in packs of 5, 10, or even 20. But most manufacturers offer their blades in large quantities of 100 or more since they’re a disposable tool that many users go through pretty quickly.
For us, the higher quantity is always the better bet. A single person can easily go through a 5-pack of blades in a few hours, but 100 blades will always last much longer.
Quantity is only part of the equation though. You also have to consider how much you’re paying for those blades. There are some brands that sell 100 blades for a reasonable price, but other brands might charge twice that. Are the blades twice as good? In our experience, the answer is usually no. So, in general, we’re looking for the most blades at the most affordable price.
One of the final points to consider when purchasing utility knife blades is the dispenser. Not all blades even come with a dispenser, but it’s something we always prioritize.
A good blade dispenser does several things. First, it keeps your blades neatly organized so they’re not rolling around loose in your bag, waiting to slice your fingers up. Next, they keep the blades clean, holding in the light oil coating and keeping mess to a minimum. They also make it much easier to remove blades without worrying about cutting yourself.
These are all important traits for a blade dispenser to have, but they don’t all perform these tasks to the same level. Some of the dispensers we used were great and allowed you to remove blades without any issues. Others were jamming constantly, making it frustrating and somewhat dangerous to remove blades.
You should also consider how many blades the dispenser holds. Some blades came with dispensers that could hold 100 blades and safely dispense them. Others could only hold 5 or 10 blades. Smaller dispensers are great for keeping blades in your pocket so you have them on hand for when you need them. Larger dispensers are perfect for the toolbox, allowing you to keep plenty of blades on the job site so you never run out.
While all of these blades serve the same basic function, they do so with varying degrees of effectiveness and longevity. Since we go through so many blades, we had to find the best ones on the market. You’ve already read about them in our reviews, but we’re going to quickly summarize our favorites once again so they’re fresh in your mind.
Our top pick overall is the Goldblatt Utility Blades. They come in a great dispenser that allows you to safely take 1 or 5 blades with an indicator so you know when you’re running low. The blades are made from durable SK2M steel with precision double-honed edges for durability.
Looking for the best value? Check out the CRAFTSMAN CMHT11921A Utility Knife Blades. They’re affordably priced with a hard-plastic dispenser to keep them organized and a precision-honed edge that offers a long cutting life.
For professionals who demand the best, we recommend the LENOX Utility Knife Blades with a high-speed steel edge and titanium coating. They feature shatter-proof bi-metal construction and a 4-notch design for ultimate versatility.
