About this item

  • Multiple Applications: Snap-off utility knives are perfect for DIY projects, home renovation, warehouse work, and other cutting tasks. Whether you're cutting cardboard, paper, or other materials, these box knives will provide you with the cutting power you need. Plus, the 4-pack set ensures that you always have a knife on hand for any cutting task that comes your way.
  • Versatile Blade Sizes: This 4-pack box knife contains 2 utility knives with 18mm blades and the other 2 with 9mm blades, providing you with options for different cutting needs. The 18mm box cutter blades are perfect for heavy-duty cutting, such as cardboard, carpet, and leather. The 9mm blades are ideal for lighter cutting tasks, such as paper, and thin plastic. With those box knives, you'll always have the right tool for the job.
  • Durable and Long-Lasting: These utility knives are built to last. The high-carbon steel blades can maintain sharpness for longer periods of time. The ABS material also provides excellent resistance to impact and chemicals, making the knives even more durable. Plus, the snap-off design ensures that you always have a sharp blade at the ready, making these box knives a reliable tool for all your cutting needs.
  • Secure Locking Mechanism: Each cardboard knife is equipped with a secure locking mechanism at the grip to ensure safe use. When the paper knife is not in use, please simply lock the blade for easy and safe storage. There is a hanging hole in the grip of the bigger cardboard knife for convenient storage.
  • Comfortable and Lightweight: These box knives all have ABS grips that feature an ergonomic design, providing maximum control and reducing hand fatigue during use. This box opener tool only weighs 2.12ounces which is very light to bring out and easy to use.

I still love these "fish gutters," what I called as a little girl... you guessed it; learning to fish; they were the fish gutters! Can NEVER find pack like this at any store, ALWAYS sold out! Watch yourself; these babies so sharp, I sliced thumb to the bone! But, that was my bad; I 1,000% recommend! I was cutting a Gatorade top; don't do that. Haha! They're durable, I use for everything, even opening DVD packaging, annoying tags on clothes, cut w/ no accidental tears (scissors); both sizes, I have them in every room in house. I use to shave worn dead " markers! Save money simply slicing outer marker, Boom! Those throw away markers kids go through so fast, get more use, simply shaving off outer layer, easy to keep marker pointed, kids don't even notice most of the time. Point downward, def over trash bin, & shave layer off, it even works w/ wooden cuticle/nail products; NEVER get dull; able to use entire stick; shave as w/markers, beat the system!!! I use small ones for that. So easy to make perfect straight line cuts (I've never been able to do before); these "fish gutters," are positively BEST, not to mention, most affordable; 4pack! Dream come true;! Cheaper than stores! Quality at this price? PLUS quantity? When does THAT ever happen! "Fish Gutters" beyond my satisfaction!

5.0 out of 5 stars Surprised at how well they work
Reviewed in the United States on November 5, 2021
Verified Purchase
Last time I ordered box cutters, I either had to buy one, or a whole bunch of them, neither which suited my needs. They are nicely made and I like the two different sizes. Nowadays with all this recycling cardboard boxes, they make a quick job of taking them apart for garbage collection. Very easy to work, just be sure to retract the blade after use to prevent getting cut. If you do not retract the blade after eery use, you might get cut or do damage to some surface. I just broke down about 30 boxes at one session and the cutter made quick work of it. HIghly recommend. Also blade is sharp, ad when it gets a bit dull, just snap it off, carefully, and voila, a new sharp blade is ready for use.

There is nothing overly special about this cutter set but it does the job nicely. I was looking for something small and handy of open my numerous Amazon packages and this fits the bill perfectly. It's slim and stores nicely. Excellent value for a 4 piece set. Added bonus of additional blades is perfect.
