In Kung Fu they speak of iron palm techniques. Is Yang Mian™s steel hand the same as iron palm?
They are not the same although there are some resemblances. Steel hand covers a wider range of practice and use than is usual with iron palm. Also, steel hand training requires no special liniments or medicines to toughen the hands to avoid injury. Your hands will always appear completely normal until you have to use them in self defence. Your hands will be able to break tough objects such as river stones (stronger than house bricks) if you wish to reassure yourself of their power.
