My preference in blade steels places S30V on top - but D2 is close behind! That may be why I like my 710 so much. Not the easiest to re-edge, but do-able - and worth the effort. Getting OTD for <$109, inc s/t, was a deal, too - I thought.

PS I carried the new Bone Collector for ~7 hr before getting home and removing the clip - the longest I've carried a BM with a clip!! Gads!
