Knockoff Tools Fiver is a multi-use tool for installing window film on flat glass, particularly architectural installs. It can be used as a bump stop at the edge of a window. It can be used as a cutting guide at the end of an installation. Hold a knife against an edge and slide the Fiver and knife along the edge of the window. This technique trims any extra window tint, leaving a straight edge behind. The Fiver can also be used to absorb any remaining application solution. After the bulk of the squeegeeing is done and most of the fluid has been removed, put a few layers of paper towel under an edge of the Fiver. Hold this absorbant edge against the edge of a window and squeegee out the remaining solution.

Keep your expectations in check. This tool is a simple piece of plastic. It won't train your dog or clean your house for you.
