As I mentioned on Scraper Planes, the cabinet scraper has often been confused with the scraper plane. The cabinet scraper (often called a doublehandled scraper) is designed to reduce the fatigue often associated with hand scraping (top photo). It's basically a metal body that holds the scraper blade at a preset angle, typically around 110 degrees. The blade is held in place by a pair of retaining screws, either slotted or with knurled ends (middle drawing). The traditional grinding angle of a cabinet scrapers blade is 45 degrees. This creates a sturdy burr that can take a more aggressive cut.
Just like a hand scraper, the blade of a cabinet scraper should be flexed to create the desired depth of cut—and here's where the real beauty of this tool shows. Instead of wearing out your thumbs from flexing the blade is flexed by way of a thumbscrew that's threaded through the body (bottom drawing). To adjust the flex, tighten the retaining screws with the adjustment screw slack. Then tighten the thumbscrew for the desired cut and make a test shaving. Like the scraper plane, a cabinet scraper works well on thin or delicate stock that could easily tear if a hand scraper were to catch or dig into the surface.
