The safe and efficient cutting of window blinds can be accomplished by utilizing a blind cutting system which is configured to support and contain the blinds in a desired position, and to have a cutting saw move along a cutting plane such that a cutting blade will interact with the blinds and cut a predetermined portion from an end thereof. A framework is used to support the cutting saw and allow movement of a cutting blade in a very controlled manner, thus avoiding any possibility that the blade is positioned in a dangerous position during operation. Further, the travel of the cutting blade along a cutting path will create a cutting action in a controlled and defined manner. Further, the cutting blade is shielded on virtually all sides, thus eliminating the possibility of injury or harm to a user. 1. A blind cutting system for customizing window blinds , comprising:A framework;a pair of substantially parallel rails attached to the framework and oriented in a near vertical position during operation of the blind cutting device;a cutting saw slidably coupled to the pair of rails, the cutting saw having a cutting blade which is movable along a cutting path, which is contained within a portion of a cutting plane, when the saw is moved along the pair of rails, wherein the cutting plane is also substantially parallel to the pair of rails;a holding structure coupled to the frame and positioned in predetermined position relative to the pair of rails, the holding structure comprising an adjustable support shelf, a slidable holding clamp, and a slidable registration stop, wherein the adjustable support shelf is capable of being sized to support the blinds to be cut and has supporting surface which is and normal to the cutting plane, wherein the slidable holding clamp has a clamp surface substantially parallel to the supporting surface which is movable in a direction normal to the clamp surface and the supporting surface, and wherein the slidable registration stop has a stop ...

A chop saw includes a base assembly and a saw assembly pivotally attached to the base assembly. The base assembly has a workpiece-supporting plane. The saw assembly has a blade and a motor driving the blade. A hinged connection between the base assembly and a saw assembly allows a user to rotate the saw assembly from a position where the plane of the blade extends through the workpiece-supporting plane to a position where the plane of the blade does not extend through the workpiece-supporting plane. In such position, the plane of blade may be substantially parallel to the workpiece-supporting plane.
