American steel is terrible, I'll pm my address for proper disposal. :w
Like has been said American steel is much mor abrasion resistant than Sheffield steel. The resulting shave once you get it dialed in is awesome imo. Just takes longer than you're used to to get a bevel set. Once there I would kill it lightly on the corner of your 1k hone and set again to make sure. At least that's what I started doing to new to me razors when I don't know where they have been. It has really helped keep me from having to go back for corrections after the shave test.
