I don't recall the date but there was some point in time where Belgian law required the makers to change their markings on faux damascus/twist. After this date bbls may be found marked damascus finish etc. Prior to that date I believe a bbl could be found marked damascus that in fact was not. These were for the most part the cheapest of bbls, so don't expect one of these to actually be stronger or of better quality than a "Real" damascus.
