I really love this black and white movies… Take a look at this blacksmit’s forging this huge chunk of iron under this earth shaking steam power hammer 100 years ago.  I wonder how much the iron weights, i think a few hundred kilos or maybe a ton, and this guys are moving it just using some chains and the muscles. I know this day’s there is an iron manipulator, a feeder that’s moving the iron under the power hammer taking the heavy loads from the hands of the blacksmits and mimimizingi the risks of enjury.  The blacksmiths in this movie are cutting the material using a special power hammer chiesel, you can see two of them are handeling the big chisels from the sides of the steam power hammer
