A SAFE UTILITY KNIFE: This box opener's blade is made of 100% zirconium oxide and safeguards against injury with its proprietary finger-friendly edge; keeping both the user and the contents inside the package safe. AN EFFECTIVE CERAMIC BOX CUTTER: Our safety box cutter is just as effective at cutting materials due to the blade's durability and design. Additionally, our ceramic utility blade never rusts and lasts 11x longer than traditional metal package openers. DESIGNED FOR EASE: Unlike a typical exacto knife, Slice's innovative package opener has a curved, ergonomic handle allowing for a more precise cut. It is also suitable for left and right hand users and allows for easy carry in a pocket, bag, or can be hooked on the wall. PERFECT FOR ANY MATERIAL: This ceramic utility blade is not only great for cutting through cardboard and breaking down boxes; it is also perfect for cutting a variety of materials including clamshell packaging, tape, cardstock, vinyl, and plastic film. YOU CAN TRUST SLICE: Slice remains the first choice for safety and effectiveness in industrial settings and is now recognized as the leading box-opening tool in homes.
