I saw the zKnives site (came up early on a search) and had to take a look cause he was new to me. It's a very busy place. I'd be interested in his source materials but could easily write it off as a typo.

There is so much other rich reputable data out there to look at, that one reference isn't enough to swing me away from what I thought was fairly correct memory. I really really wish Hitachi would publish simple data sheets like Crucible and so many others.
