About Slice

Slice, based in Florida, was founded in 2008 by TJ Scimone.

TJ Scimone, founder of Slice

Always looking for new ideas, he collaborated with renowned designers to reimagine everyday cutting products, making them safer and easier to use. Since that time, Slice has developed a collection of award-winning safety cutters that increase productivity, lower costs, and, most importantly, reduce injuries. Slice tools are now used in major industries around the world.

Scimone founded Slice as a way to help fund long-term care for his autistic son. One percent of all Slice sales are donated to autism research.

At Slice, we know what’s important. We value safety, innovation, quality, simplicity, and community. These core values are evident in everything we do, from tool design to customer service.

Slice Values

These are the ideas at the heart of the Slice brand. They guide us in every aspect of our business.

Safety: reducing injuries and preventing accidents
Innovation: rethinking safety; fresh perspectives in all we do
Quality: creating quality products and quality relationships
Community: giving one percent for autism research
Simplicity: creating intuitive, easy-to-use products; clear communication with our customers


Fresh Thinking = Smart Design

Slice’s innovative tools reflect our fresh thinking. We collaborate with acclaimed designers to reimagine every aspect of tool use from the perspective of safety, ergonomics, and efficiency. The result is a cleanly-designed line of durable, effective, cutting tools.

Slice makes safer versions of traditional tools like box cutters, utility knives, pen cutters, and craft knives. We've also developed ceramic micro-blade technology with innovative tools like our Precision Cutter and Safety Cutter. Whenever possible, Slice tools are ambidextrous and offer tool-free blade replacement.

Slice, Inc. is a proud member of the American Society of Safety Engineers and the National Safety Council.


Our Safety Is in the Blade

Only a small portion of the risks users face are addressed by new handle designs, which is why Slice redesigned the blade.

Most safety cutter brands look for new ways to design their handles. While these innovations are helpful, they don’t solve the core problem. After all, what cuts you: the handle or the blade? Slice went back to basics and developed a safer blade, using advanced ceramics.

Because steel is a relatively soft material, it dulls quickly. To give steel blades a useful working life, manufacturers sharpen it far beyond what’s necessary. This workaround sacrifices worker safety for longevity. Slice uses 100 percent zirconium oxide, an extremely hard material that doesn’t need to be oversharpened in order to maintain its edge. This allowed us to develop a proprietary grind that creates a finger-friendly, touchable blade that holds it edge an average of 11.2 times longer than steel.

The initial cutting zone is defined as the part of a blade’s edge that does the actual cutting. This zone is a result of the angle used to grind the blade. In a metal blade, the smaller angle creates a longer and sharper cutting zone, making users much more vulnerable to lacerations. Slice uses a patented double grind that shortens the cutting zone significantly. This creates an effective cutting edge that doesn’t endanger the user.

Slice blades are wider and include a small micro edge that does the actual cutting. The grind angles create a blade that cuts materials effectively, but resists cutting skin. Slice blades disperse their pressure, requiring much more force to pierce skin’s tough outer layer than narrow steel blades.

Slice ceramic blades offer many other advantages over steel. They:

  • Never rust
  • Are chemically inert
  • Don’t require any oily coating or lubricant
  • Are safe up to 1600 degrees Celsius
  • Are non-sparking, non-conductive, and non-magnetic
  • Are maintenance-free
  • Don’t require sharps box disposal
  • Are recyclable
  • Are safe for clean rooms
