The Slice Micro Safety Cutter is a small, lightweight box opener built for everyday package opening—without the “one slip and you’re bleeding” vibe of many traditional blades. Its minimally exposed micro-blade is made from 100% zirconium oxide and features Slice’s proprietary finger-friendly edge to help reduce accidental nicks while still slicing through tape, mailers, and packaging.

This 2-pack (Green) is easy to keep where you need it: stash one in a kitchen drawer for food packaging and clamshells, and clip the other to your keys for quick box opening on the go. The rubberized, non-slip handle material and ergonomic design make it comfortable to hold even for quick, repetitive cuts.

Unlike metal blades, Slice’s ceramic blade won’t rust, and the brand states it lasts up to 11x longer than metal package openers—helping you cut down on replacements and keep a reliable opener close at hand.

  • Minimally exposed micro-blade with a proprietary finger-friendly edge to help protect fingers and package contents
  • 100% zirconium oxide ceramic blade that won’t rust
  • Designed to open boxes, tape, mailers, food packaging, and plastic clamshell packaging
  • Compact 2.41-inch, lightweight (0.21 oz) design suitable for keychain carry
  • Rubberized, non-slip handle material for secure everyday use

If you open a lot of deliveries (or just want a safer, more convenient cutter around the house), this tiny tool is an easy upgrade from bulky utility knives—especially when you want control without a fully exposed blade.
