Now a renowned mechanic with his own workshop in Pakistan's sprawling metropolis of Karachi, Patel's story is a rare tale of success in a country which offers few opportunities for the blind.
At a small workshop that employs seven people in the city's Lasbela area customers come and go, leaving their their cars in the trusted hands of their old mechanic.
"I used to play with those things and I used to break them," he tells AFP of his childhood.
"Whenever my dad brought things I would open them up, then try to fit it back how I opened it, and I saw how it worked."

Pakistan has nearly two million blind people, according to the Fred Hollows Foundation, with more than half afflicted due to treatable conditions like cataracts.
Opportunities for the blind, like those with other disabilities, are few and far between, with many sight-impaired reduced to begging on the streets to make ends meet.
Not so for Patel.
"No, I was encouraged at home," he says.
The key to his success, he explains, is his keen sense of touch. "It is important for us that we touch, and see how it is, and what it is."
After dropping out of school, he found a part-time job at age 15 at an auto-workshop and was assigned the task of dismantling a clutch plate.
The next part of his training involved taking apart a gear box.
"I said 'yes' and lay under the car and saw that the clutch plate we opened was put in with a flywheel and the area behind it is the gear," he said.
"So mentally I figured out the rounds of the gear and its foundations and in barely 15 minutes, I took it out and was done.
"When I opened and put the gear out, I gained their trust and they knew that this boy had some gift from God and could do this work."
