The blacksmith in this video has a nice rhythm and utilizes the horn of the anvil to create the bends for his S hook. He manages to do the entire hook in one shot. That kind of speed and skill is helpful when you’re trying to create a lot of hooks to fill an order.
If you take a look at his forge setup, you notice that he has two fire bricks at the front that he can move around. My guess is that he uses those two bricks to close off his opening to build more heat. Also, check out that viking shield on the wall.
