To keep myself occupied, I'm going through the Foley-Belsaw course and the first impressioning you do is a Master warded padlock (No. 22?). I've completed the hands on exercise twice, the second key looks much better than the first (but they both work).
I'm not using anything fancy, just a table-top vise, hand pressure, and the two files that were included in the course package.
It's also interesting to learn the theory behind things that I've "known" for the last 30 or so years but never been specifically taught.
