The Guardian Knife Guide is safer than other knife guides, more accurate and more cost effective. You can score cut, plunge cut, angle cut and make repetitive cuts. The customized extrusion allows the user to line up the blade by lining up the side of the extrusion for easy trimming of prints along the edge. The knife bracket has a flair on one side so the user can quickly mount the knife on the guide extrusion. The guide extrusion has a lip so the hold down hand of the user will not contact the knife bracket while in use. The bottom of the guide has non-slip rubber so it doesn't slide on your material. Great for cutting or scoring vinyl, Coroplast, Gatorfoam, banners, board stock, cardboard, PVC foam, sign foam, laminates, carpet, drywall, fabric, or whatever you would cut with a razor knife. Includes OLFA knife, knife bracket, and aluminum guide extrusion that has non-slip rubber on bottom.
