This tool began as an inspiration from our daughter-in-law. She was looking for a way to simplify removing tool marks and produce a straight wave free buttery smooth finish. Hence the development of a wide carbide scraper that was simple to use, arrive sharp and stay sharp for a long time . . . the carbide Simple Scraper. Beneficial on every project from small pens to large bowls and everything in between because you can shape and finish with a single tool. Quickly remove tool marks and create silky smooth profile transitions between inside and outside curves, as well as straight wave free lines. Makes a perfectly flat bottom with a smooth transition to the inner wall using the oval cutter, or a square inside box corner using the rectangular cutter. Creates a smooth finish with much less tearout and minimal sanding. Benefits: The widest and most unique carbide scraper on the market.
