We all know that the difference between a project running smoothly, on budget, and on-time, or running behind, over budget, and frustratingly, can come down to the quality of the tools which you use. You don’t even always need the best tools, but rather the right ones for the job.

Unfortunately, finding the right tools when shopping online can be a tall task. Manufacturers are all too happy to sell you a product that doesn’t work well and laugh with their profits all the way to the bank.

That’s why our reviews are designed to show you the good and the bad on each model. That way, you’ll be able to get tools you’ll like using, and with our guide, you’ll be able to get them at a great price, too.

3 Best Drywall Knives

1. DeWaIt Drywall Knife with Blades – Best Overall

DeWaIt Fixed Blade Drywall Utility Knife with 15 Blades

While not every tool is designed with the professional in mind, the DeWalt Fixed Blade Drywall Utility Knife with 15 Blades has a lot of features that most people will value. It comes with a soft grip, which doesn’t sound like that big of a deal, but if this is going to be a tool that you use all day, you’ll want one which doesn’t completely wear your hands out. It also makes use of extremely durable carbide blades, and hold their edge better than blades made of lesser materials. This model comes with onboard blade storage, so you’ll be able to store up to five additional blades in the handle, which reduces the time it takes to change out a blade.

This set also comes with 15 total replacement blades, so you’ll be able to use this tool for weeks or months before you need to buy new blades. The only problem with this model is that it can be hard to unscrew at times. It’s designed to be opened with your thumb, but some users have found that they need a screwdriver. Still, this is easily the best utility knife for drywall cutting.

  • Lots of replacement blades
  • Soft grip
  • Carbide blades
  • Onboard blade storage
  • Hard to unscrew

2. Stanley 15-556 Drywall Knife – Best for the Money

Stanley 15-556

The Stanley 15-556 is a great jab saw that makes cutting drywall quick and easy. It comes with a huge blade, which removes a lot of material per pull, leading to very fast cutting. The blade is also tempered, so you can expect it to go a very long time due to its exceptional strength. It also comes with an ergonomic handle. It’s not quite as comfortable as the one found on our previous model, but it is shaped in a way that will let you go longer without any kind of discomfort. Best of all, you can get this model for half of what you’d pay for the previous one, which makes this model the best value for the money on our list.

However, there is one significant downside to this model, which keeps it out of first place. The end is angled, which means you can’t use your hand or a hammer to drive the saw in or to get it started once it’s in the drywall. It’s a small inconvenience that happens a lot and will have a noticeable impact over time. However, if you’re looking for a great deal, you can’t go wrong with this model.

  • Jab saw
  • Tempered blade
  • Ergonomic handle
  • Great price
  • Angled end

3. DEWALT DWHT20123 2-in-1 Folding Drywall Knife

DEWALT DWHT20123 2-in-1 Folding

The DEWALT DWHT20123 2-in-1 Folding Jab Saw/Rasp Blade is the model you should get if you can make use of a jab saw and a rasp blade. And while many people may not think that they’ll use the rasp much, it excels at cleaning up edges in a way you could never achieve with a saw by itself. This model also makes use of a folding design. Both blades can be extended and retracted back into the handle, keeping them out of the way when they’re not in use. That also means that this model folds down for travel, protecting the blades, and since it’s smaller when folded up, it’s great smaller toolkits.

The handle is also comfortable and might be the most comfortable one on our list due to its rubberized exterior. However, the blade has some lateral give. That’s not a big deal if you’re using this tool on a quick project, but if you’re going to be working on a project that requires dozens of cuts, you’ll probably want something more solid. Overall, this is a decent drywall knife, and while it may be good for home use, professionals may wish they had a more reliable tool.

  • Dual jab saw/rasp
  • Folding design
  • Ergonomic handle
  • Not great for large jobs
  • Has give

Buyer’s Guide

When it comes to buying drywall knives, there are two features you should heavily focus on: comfort and durability.

Comfort may not be the first attribute which leaps into your head when you’re thinking about tools, but if you’re buying something, you’re going to be using all the time, it makes sense to buy something which won’t wear you out quickly. Plus, comfortable tools reduce accidents, since you won’t be using them incorrectly to reduce the strain on your hands or body.

The other big factor is durability. A lot of this comes down to the blades which you choose. Carbide blades tend to be the best available for manual saws, and they both cut well and hold their edge for a very long time. You also need to pay attention to the quality of the handle. A handle that breaks just a few hours in costs you a lot of value, since you’ll have to replace the entire thing, as opposed to with the blades, where you only have to replace the blades.

RELATED: which utility knife is our all-time favorite?


The DeWalt Fixed Blade Drywall Utility Knife with 15 Blades is our favorite drywall knife due to its soft grip, use of great carbide blades, and the 15 replacement blades included in the initial price. In second is the Stanley 15-556, which is a great jab saw with a tempered blade and an ergonomic handle, though its angled end drops it to second place. We also like the DEWALT DWHT20123 2-in-1 Folding Jab Saw/Rasp Blade, which comes with both a jab saw and rasp arranged in a folding knife configuration, though the give in the blade makes it a poor choice for big jobs.

We hope that our reviews and buyer’s guide have helped you see what makes for a great drywall knife. You should now be able to find the model which is right for your next project at a price that won’t break the bank.
