Found it in the post where Dan announced the LE version :

If you plan on using your Scrapivore for more abusive types of work such as batoning, point prying, etc., we suggest you consider the Scrapivore Combat Grade (Coming Soon). With a slightly thicker blade and a much more rough and tumble hardness of 58-60 Rc, the Combat Grade Scrapivore is ready to handle anything you can bring its way.
