ABSTRACT:
An apparatus and method for cutting rolled window shades, and the rollers on which they are mounted, includes a cutting member with a cutting edge and a support member with a supporting bed rotationally coupled to each other by a pin and elastically biased toward each other. Each member has a handle with a finger indentation to provide for turning of the cutting device circumferentially around a shade and roller positioned perpendicularly between the members, at a location where a cut is desired.
