Slice's mini ceramic box cutters offer a safe and effective way to open packages and break down boxes. This 2-pack includes the 10514 model with an auto-retractable blade that stays sharp up to 11 times longer than steel, and the manual-retracting mini cutter with the same long-lasting ceramic blade. Both feature finger-friendly edges to protect hands during use. The 10514 auto-retracts its blade when not in use for safe storage. Its extremely hard zirconium oxide ceramic blade retains its sharp cutting edge through many uses without rusting or conducting electricity. The built-in magnet and keychain hole allow convenient storage within quick reach. The manual mini cutter has the same durable ceramic blade that never rusts. Its proprietary finger-friendly edge helps guard fingers while cutting. The lightweight design is great for portability and home use. Together these complementary cutters tackle all your packaging needs. Use them for opening boxes, food bags, plastic containers and more. Slice's ceramic blades have been tested and trusted to be safer and longer-lasting than traditional metal cutters.
