Abstract
A box top opener employs a trapezoidal ceramic blade having a cutting edge which is positionable at multiple positions. A knob is rotatable to extend and retract the blade. A guide projects from a front of the cutter body to provide a guide surface engageable against the top of a box. In one embodiment, a blade carrier has a follower which traverses a spiral track for displacing the blade.
