I made a knife under the guidance of someone who knows what he's doing which was a lovely experience. It kind of went where it wanted which was weird but still ended up as usable. I also tried with a bit of stainless rebar which was horrendously hard.
Uri Hofi has a dvd on how to use the hammer he sells which is not big, but his "system" I think is meant to cover pretty much anything without heavy thumping and so no arm damage. Not seen it myself, but have tried his hammer which was recommended at the time.
