GT Tools® took the functionality of a long knife and transcended it into a new design that’s ready to devour urethane. The Quarter Cutter™ excels in cutting hard to reach corners and is perfect for quarter glass! Made from a durable aluminum body and knurled steel Power Handle, this tool can be driven through the urethane using a pushing motion; if that’s not good enough, use the Power Handle and a rubber mallet to slice through crusty old urethane!
