This hand scraper has a metal knob handle that can be hammered with a rubber mallet to scrape up hard spots. The knob has rounded edges to fit the palm. Handle is 18" long for working effectively with both hands and for extra reach. Comes with a 5" wide blade with the same .037" thickness as our heavy-duty Big Scraper blades. The scraping head is steel-reinforced, and the blade clamp is fastened to the head with three case hardened slotted head screws.
