Description
Scraping flat bottoms and establishing true 90-degree corners requires a blunt, stable edge. This 1″ square end chisel is designed for truing up straight tenons and smoothing box bottoms, providing a heavy profile that rests securely to prevent catching. It is the perfect scraping tool for finishing flat surfaces inside bowls or boxes where a gouge cannot leave a perfectly level floor.
