1、Arch Blade: The scraper holder can make the blade bend shallowly, providing a wider cutting area and premium control to ensure better results. 2、Easy to Use: This hand scraper easily keeps you away from scratches. Pull out the arch screw and loosen the two locking cone screws. The cone screw may automatically lock into place, gently press the top of the locking screw, and the cone screw will unlock. 3、Simple to Install: Invert the scraper holder, lift the locking cone screw upwards, and slide the scraper blade between the flat part of the locking cone and the semi circular pivot point. 4、Versatile Use: If necessary, insert the scraper holder completely or partially, and then only turn the locking screw until each cone gently grips the scraper, allowing the cone to rotate when the scraper bends. 5、Aluminum Alloy Material: The scraper is made of aluminum alloy material, ensuring durability and stability for long term use.
