This video demonstrates the draw filing technique for preparing steel surfaces, a crucial step before cold bluing. The instructor emphasizes that draw filing involves drawing the file towards you, not drawing with it, to flatten uneven surfaces and remove imperfections. This method is presented as an alternative to buffing wheels, which can sometimes cause more problems. The process begins with a rough steel piece and progresses towards a smooth, flat surface ready for finer grit sandpaper.
