When you need to replace the blade in your BTC-1/DX Multi-Purpose Scraper, choose the OLFA BTB-1 43mm Scraper Blade. Scrape, cut, shave, or slice with this dual-edge blade manufactured of Japanese tool steel. When one edge dulls, simply rotate 180 degrees for a fresh edge.
One edge is blunt for tough demolition while the other is razor sharp for fine scraping and cutting.
