Using Blades Backwards

Last year I needed to cut plexiglass. The standard technique of mounting a circular saw blade backwards worked great.

Today I needed to put grommets in thick canvas. The grommet kit came with a "cutter" to hammer through the cloth but it did not work at all. I experimented with a few ideas, and found that a spade bit worked great: normally until the point went through the fabric, then backwards to widen the hole without the fabric catching.
