Cordless Utility Knives That Cut the Cord and the Work
The Milwaukee 2470-20 M12 Cordless Utility Knife is the top pick for most tradespeople because it cuts drywall and roofing at a rapid pace with minimal hand fatigue. Its main advantage is the one-handed blade advance trigger that keeps your other hand free for steadying material. The main limitation is that it uses M12 batteries, which adds cost if you are not already in that system.
Cordless utility knives are changing the game for professionals and DIYers who need to make repeated cuts without gripping a handle. These tools use a motor to oscillate or advance a standard utility blade, dramatically reducing hand strain compared to manual knives.
We compared the most popular models available today, focusing on real-world performance, battery life, and durability. Whether you are cutting drywall, carpet, or roofing, there is a cordless knife that fits your workflow.

Common questions
What is a cordless utility knife used for?
A cordless utility knife is used for cutting materials like drywall, roofing, carpet, insulation, and cardboard. It reduces hand fatigue and speeds up repetitive cutting tasks compared to manual utility knives.
Are cordless utility knives better than manual ones?
For professionals who make many cuts daily, cordless knives are better because they reduce hand strain and increase productivity. For occasional light use, a manual knife may be sufficient and less expensive.
What type of blades do they use?
Most cordless utility knives use standard utility blades (trapezoid blades) that are widely available and interchangeable. Some models may accept specialty blades for specific materials.
Can I use my existing power tool batteries?
Yes, if the cordless utility knife is from the same brand and battery platform as your existing tools. For example, a Milwaukee M12 knife uses M12 batteries, and a DEWALT 20V knife uses 20V batteries.
Are cordless utility knives safe?
They are safe when used properly. Always follow safety instructions, keep your hands away from the blade, and use the blade guard when not in use. Some models have safety triggers to prevent accidental starts.
How long does the battery last?
Battery life depends on the battery capacity and the cutting conditions. Many users report being able to cut for several hours on a full charge with a standard battery. High-capacity batteries extend runtime.
Do I need a special blade for different materials?
Standard utility blades work for most materials, but for heavy-duty cutting, you might use a carbide blade. Some cordless knives allow you to use various blade types for different applications.
Can I use a cordless utility knife for cutting curves?
Cordless utility knives are generally designed for straight or long cuts. For curves, a manual knife or a different tool like a jigsaw might be more suitable. The oscillating action makes it hard to steer.
What is the difference between oscillating and reciprocating cordless knives?
Oscillating knives move the blade side to side at high speed, while reciprocating knives move the blade back and forth. Most cordless utility knives are reciprocating, providing a sawing action. Oscillating multi-tools can also cut with a specialty blade.
Are cordless utility knives worth the money?
For tradespeople who cut materials daily, the time saved and reduced hand fatigue make them worth the investment. For occasional DIYers, it depends on how often you cut and whether you already have compatible batteries.
The bottom line
For most professionals, the Milwaukee 2470-20 M12 Cordless Utility Knife is the clear winner due to its lightning-fast cutting speed and proven reliability on job sites. If you need more power and already use DEWALT 20V tools, the DCS385B is an excellent choice. For DIYers on a budget, the CRAFTSMAN V20 offers solid performance without breaking the bank. Choose based on your battery ecosystem and the intensity of your cutting tasks.
