I wikied "katana" and there is a lengthy, although disouted article on blade making and they set the limit at folds between 8 and 12, never more than 20.
the reason for folding has more to do with creating a homogenous mix of steel and carbon and burning out impuritites from the poor steel.
but then it is wikipedia
