With the appropriate attention to technique and careful use of materials, any amateur should be able to produce a high-quality optical surface. Recently amateurs have begun trying unconventional polishing techniques such as oversize tools, narrow and fewer channels, different channel patterns, random microfaceting with a razor blade, urethane polishing pads for polishing speed, and different polishing strokes.
