Foley videos on YouTube and elsewhere

A recent web search found some new and better videos of Foley equipment in use. Here's a good one by Chris Schwarz, showing Tom Calisto cutting backsaw teeth on a hand-cranked Foley retoother at The Woodwright's School. While you are at it, search YouTube for Chris Schwarz's many videos on sharpening and woodworking.
