ABSTRACT:
A cutting system utilizes a cutting blade-holding base that removably holds a number of long razor cutting blades in a corresponding number of longitudinal slots. A replaceable blade knife of the cutting system has a cutting blade-gripping member with a bifurcated lower region extending throughout its length and dimensioned for resiliently gripping one of the long razor blades. The blades are placed within the blade-gripping member of the cutting knife by placing the heel end portion of the bifurcated region over the razor blade at this point and then angling downward so that the remainder of the bifurcated region resiliently grips the cutting blade throughout its entire length. The cutting blade-holding base also serves to store the knife with its cutting blade by insertion of the blade into an empty slot of the base. Removal of the cutting blade from the knife is accomplished by placing the blade in an empty slot of the blade-holding base and sliding the knife backwards so as to engage the cutting blade with a blade-stop portion of the base; whereby the cutting blade remains within the slot of the base while the knife slideably disengages from the cutting blade.
