About this item

  • GEARYTE CERAMIC UTILITY KNIFE replacement blades are razor sharp and will cut through standard packaging materials with ease. Strong, long wearing Zirconia Ceramic material stays sharp even after extended use.
  • CERAMIC BOX CUTTER REFILLS will stay sharp up to 10 times longer than a steel razor blade. Ultra strong Zirconium Oxide (Zirconia) ceramic will not spark or rust, making it a safer option than other blades in some applications.
  • GEARYTE CERAMIC UTILITY KNIFE blades will cut through tape, paper, cardboard, plastic and nylon and fiber strapping materials with ease.
  • CERAMIC UTILITY BLADES will keep an edge longer than a steel blade but are also easier to break under stress. It is advised that you only use ceramic blades for cutting and slicing only and do not use them to pry things or use the blade as a screwdriver or chisel.
  • GEARYTE CERAMIC BLADE box cutter and utility knife blades refills come in a reusable plastic case that provides protection for the blades and a convenient storage option.

I like these for seams on countertops that are made out of other materials, but most importantly white stone. It doesn't stain seams and cause metal marking. They lasted me a long time. Great in situations where you have to scrape glue out dirt out but you need to avoid contaminating or staining the material.

I was super against ceramic blades. My company requires them but they always get the Slice brand and since that was my only experience with ceramic blades I thought they were crap.Finally I decided to give these a try. Wish I would’ve tried earlier, this thing is so sharp and stronger than regular blades. I’ve only used it a day or two but I’m told it’ll even last longer than razor blades! 10/10

Just broke my third one in 2 days slicing plastic wrap. These cut great while they last but I just had my third one break in the last 2 days while cutting open plastic wrap. For what these cost they should be a bit more durable. These are almost translucent in how thin they are. Being a little bit thicker would probably make them a better product

[CAUTION] Always wear safety glasses when using these blades. As noted in the description, “Ceramic utility blades will keep an edge longer than a steel blade BUT are also EASIER TO BREAK UNDER STRESS.”This is my first time using ceramic utility blades with my Stanley utility knife. I tested them on cardboard, and they performed pretty well, though I found they require a bit more effort compared to metal blades. I primarily use my utility knife for breaking down Amazon delivery boxes for recycling, so only time will tell if ceramic blades are worth the investment. So far, they seem decent.

I bought these mainly because the metal blades I used would always get rusty. These being ceramic do not. I don't do any heavy duty cutting, so work well for me on boxes and packages.

These ceramic blades are so much sharper than the steel blades we're all used to. And they last a lot longer, too. The times as long. I threw away the packaging so I'm not sure, but you have to know how to handle the knife.It's not for chopping of any kind. It can not tolerate twisting. Don't even think about using it for prying.But for piercing plastic and for slicing through cardboard like butter, these blades are superior.Depending on what kind of work you're doing with it, why not wear a pair of safety glasses while using? Mine have been fine so far (knock on wood) but when ceramic shatters it can send little razor sharp pieces flying through the air so I like to have a nice, clear plastic barrier between my eyes and whatever I'm using these blades on.Enjoy the rust-free ceramic blade lifestyle!

I was a little concerned these would be too thick to fit in my favorite utility knife, but they do. When first cutting, they are scary sharp. They cut better than the steel blades, and last longer too. I used them to cut up a bunch of boxes for recycling. They sliced through the cardboard like butter. They are expensive, but you won't need as many as the steel ones.
