>Thanks Frank,

I've never found much useful information about it on the web or in print either. I've learned by watching various japanese smiths doing it, at first just by watching videos, but now more by watching in person and then having to do it myself. It's called "hizumi tori", which translates as "to remove distortion". First scrounge yourself something to use as a wooden anvil.
