A brand new tool to the window tint industry. This "Shank" may at first glance resemble an ordinary plastic knife, but it is definitely a tough, useful tucking tool. This new tool has an offset installation tip for reaching behind gaskets while keeping your hands out of the way.  It is 7" in overall length with approximately 3" of flexible blade.  Made of lightweight, yet extremely durable plastic, it is great for tucking film behind those tight door gaskets
