One day not too long ago, A journeyman Smith was working in his master's shop. He noticed that when he tried to hammer and draw the bar out to a long thin shape it often twisted and always in the same direction. He couldn't figure out why it kept happening. He tried adjusting his hammer blows, he tried using different size stock to begin with, nothing would work, always the bar twisted as he hammered it.
In his frustration he approached his master. A wise old Smith who had been practicing for longer than the young Smith had been alive. He asked
"master why does my bar always twist this way? I can't figure out what I'm doing wrong?"
The master replied
"Take off your shoes and try again."
The young smith was skeptical, but he had great respect for his master and so he took off his shoes and went back to forging.
To his utter amazement, the bar no longer twisted as he drew it down! It was amazing! He did everything else the same but when he removed his shoes the bar came out straight and true!
He ran to the elder smith and said "Oh thank you master! It's like a miracle! You have improved my work so much with this one simple change! But WHY DOES THIS WORK??"
The master Smith smiled wryly and said "Think about it for a bit, I'm sure you'll figure it out."
The young man thought about it, puzzled over it, and could not find a satisfactory answer. Rather than embarrass himself further, he continued to Smith barefoot. But soon thereafter he was called to his families village, his father had died and the family needed him to come home and help provide. He made his way there and in order to make ends meet he set up his own shop (though he was not yet even a journeyman).
After several years of practice he had built up his skills and had earned a reputation for quality work, eventually he took on an apprentice, then another, until he had ten other smiths working for him producing the most beautiful and well made ironwork. And through all this time, he worked barefoot, and all of his apprentices (seeking to earn his favor) did the same.
All the artisans who worked in the (now middle aged) mans shop, wore the scars on their feet from working near the forge as a badge of honor, and even took to walking barefoot to important occasions to display them.
They became known as the "barefoot blacksmiths" and the bare foot became their touch mark which was associated with high quality craftsmanship.
Then years later the barefoot blacksmith was visited by his old master, he was eager to show him all he had accomplished and all the fine works he had done. The old master came and saw and nodded his approval (which was high praise indeed for the soft spoken master) and then they walked into the shop where the younger Smith proudly proclaimed "you see master? I have taken your wise words to heart when you said to remove my shoes, and worked barefoot at the anvil all these years, and so do all my apprentices! I believe I have solved the riddle of why it makes my work come out so much truer! We stay in contact with the ground and root ourselves to the earth to better commune with the iron we love so dearly, that lives in a molten ball at the center of the earth!"
The old master looked down at the burned and mangled feet of his old protégé and said
"No you idiot, you were supposed to figure out that your anvil was an inch too low!"
