Abstract: The present invention comprises a surface on which to place the insulation that is almost flush with the floor minimizing vertical displacement of the fiberglass. A hinged design allows a top member to compress the insulation. A machined slit provides a location for a cutting implement to be inserted and the insulation cut. Extending past the machined slit, the top portion provides a location where the user can rest his knee. Thus, an efficient cutting angle can be easily achieved and if needed more force can be used to further compress the insulation. A flange positioned at the end of the cutting slit protects the user's knee from the blade as well as any airborne insulation particles. It is also smaller than most other proposed solutions and so more easily stored and transported by a home owner or a professional from job site to job site.
