Sorby Shear Scraper

The square section of the tool shank ensures that the cutter tip is always presented at 45 degrees. This is known as shear scraping and ensures that the fibres of the wood are peeled away to leave a very fine finish - sanding may not be necessary.
There are two shapes of tip - one for internal work, one for external. The tips are fully interchangeable on the tool shank. Sharpen with a diamond hone.
