What artisans have you met in your city who are committed to their craft?

In my city, I have met a very serious craftsman. That's the master who repairs bicycles, I remember knowing him since I was a little girl because his stall was a must for me to go to and from school, and I think that after so many years, he still goes to fix bicycles for everyone as he always does, and it's also very affordable. And he's very good at fixing bikes. It can be said that after repairing once can definitely be parked for some years, so many people go to take care of his business.
