Product Description

Product Description

The Slice 10515 Manual Mini Cutter is one of our most versatile cutting tools. Useful in industrial and home settings alike, the 10515 features an integrated magnet so it’s always handy. As with the auto-retractable version, the Manual Mini Cutter uses Slice 10404 or 10408 Box Cutter Blades with our patent-pending finger-friendly safety edge. Our technology allows the blade to cut effectively while staying safe to the touch. This powerful multi-tool can be adjusted for right- or left-handed use. Slice safety blades last up to 11 times longer than comparable metal blades and will never rust.

Why Ceramic Blades? Hardness & Sharpness.

On the Mohs hardness scale, Metal blades are rated 5.5 vs. Ceramic blades at 8.2, second only to diamonds. Harder edges maintain sharpness longer, cut better, and require replacement far less frequently. In fact, depending on use, you can go weeks or months without having to replace a single ceramic blade. They also last up to 10x longer!

About the Startup

Describe your products in 3 words.

Safe. Elegant. Innovative.

How did you come up with the idea for this product?

Slice has a commitment to donate 1% of all sales to fund Autism research.

What makes your product special?

Our proprietary blade manufacturing process combines a unique sharpening angle and thicker ceramic material, resulting in a very unique patented blade that’s safer to the touch vs. metal, and requires pressure to initiate the cut — via our handles. Hence, general blade handling and blade-replacement with Slice ceramic blades is infinitely safer vs. those same activities with traditional metal blades, yet still allows for a wide range of cutting applications.

What has been the best part of your experience?

You can’t simply duplicate a metal blade in ceramic material and achieve what we have created with our current products. There’s a tremendous amount of engineering required on not only the blades and handles individually, but there’s also an incredible amount of engineering required on the combination of the handles and the blades working together in order to produce the desired balance of safer-usage and cutting capability. Even today, for our next generation of products that are currently under development, we spend the majority of our time finding the right balance between handle and blade through trial and error and what seems like endless prototypes. The best part definitely has to be seeing peoples first-time reactions when cutting cardboard with Slice and they realize how awesome the Slice ceramic blade is.

    The blade outlasts the housing.
    I love this little box cutter. I have cut the tops off of sooooo many boxes, hundreds a day sometimes and we'll this thing absolutely performs. I cut boxes faster than any other person around who has those lame penguin cutters. This always cuts smooth, fast, and super easy. I LOVE IT.With that said, this is my second one, and I cut hundreds of boxes a day sometimes, and as you can see the wear on the blade housing is giving way to the point I always have my blade "open". Its not as safe but I cannot give up this beloved box cutter.I am going to buy a new one, the green one that retracts so I'm compliant at work and I will continue to do so with the hopes that one day, they or someone else makes a blade of similar quality in a better housing that is as convenient to carry as this one.If you want a box cutter for your house and see yourself cutting a much smaller amount of boxes than I do at work, let me tell you this is the one you want. If at work you can get away with less safe box cutters, they're probably a better option as this housing degrades so quickly. I will suffer with the best I have to work with, because with cutting as many boxes as I do, I always want them to perform as well as this one does every single time.Please slice, make a more durable housing for this model 🙏🏻
