Particular embodiments of the inventive technology relate to apparatus and methods for cutting multi-layered material to reconfigure it so it may be used to construct sub-compartments in a larger storage container. The inventive technology, in particular embodiments may feature one or more of the following: dual blades, “staggered” blades (where one blade is more forward than another), a blade(s) angled upwards and forwards, blades separated in a left-right direction, prong recesses to accept trailing tips of blades, a rearwardly angled handle and/or a removed material ejection ramp, in conjunction perhaps with other features such as, e.g., a guide prong. One or more of such features may appear in the various manifestations of a defluting cutter or through cutting apparatus, whether guided or unguided, and/or manual or powered.
