Universal knife that can also act as a scraper. Modeled on a medieval Japanese leather cutting tool. This modern counterpart is also great for cutting hard materials. As a result, it has gained recognition in the upholstery, saddlery and plastics industries as a tool for cutting, shearing and bevelling edges. The solid structure guarantees comfortable work even with very hard materials. The knife has a blade lock, which ensures full immobilization of the blade. The tool is also perfect as a scraper for cleaning smooth surfaces. The BTB-1 43mm wide replaceable square blade has two very sharp cutting edges protected by a steel guard. Changing the blade does not require an additional tool.
