ABSTRACT:
A cutting tool for sheet material, especially for opening cardboard cartons, has a disposable blade removably fixed to a handle and a guide member of bent wire also fixed to the handle for keeping the blade in cutting engagement with the sheet material and away from the contents of the cartons. A nose of the guide member is rounded to avoid damaging the carton contents and projects ahead of the cutting edge of the blade. One arm of the guide member is above the blade tip so as to keep the blade from disengagement from the sheet material. Another arm of the guide member is below the tip of the blade for preventing cans or other cartons contents from being cut by the blade. A hard point is provided for puncturing cartons which are too tough to be punctured by the rounded nose of the guide member.
