Kung Fu movie with swords?

Not sure if it's a Kung Fu movie exactly, and think it might be from the 90s but there's this temple or society were they have sword fighting techniques and the bad guy infiltrates them or learns/imitates all their techniques. Think he had a 'Scorpion' style that imitated them all. So well the good guy had been sent to the blacksmith as punishment were he learns a technique of fighting with the sword blade facing down by holding the handle in a way that the pummel is facing up, think they might of called it the 'underhanded technique'. And using this technique he defeats the bad guy.
