I will say holli4pirating has the best answer on this.

The question is how or why this was started remains. I will answer...

While it was adapted into a type of "license", if you will, it was started by accident, more so out of argument. There are a couple of variations of the story. To elaborate on the story started by holli, the barber began arguing with the salesman saying he was the best barber and wanted a special razor which everyone could identify him by. A request for a custom blade so to speak. The salesman, needing to make the sale, said he would do something that had not been done to any razor and would surely be sought after.

The brilliant salesman jogged to the nearest blacksmith, grabbed his file and created a notch. The notch was brought back to the barber and quickly agreed upon as a likeable item. They coined the "barber's notch". As this quickly became a conversation piece, the barber's business really began to take off. All the people wanted to see this notched razor which was legended to be the sharpest of them all. Other uses and such for the notch began circulating after that.

The other story is the barber actually dropped the razor on its end and damaged it, he then took a file and created a "notch" in an e'ffort to make the chip that was created look more "natural". People would always ask about it when they were shaved. It just caught on and was adapted into what we see today.
