Tools for specific needs can be expensive or hard to come by in some places in Africa. It could be something as simple as a certain sized wrench that is needed to remove a particular bolt.
I decided to take a short walk in Nairobi and just see what caught my eye. Bernard runs a small engine repair shop on the outskirts of Nairobi, Kenya. Mostly, he fixes lawn mower engines for the wealthy people living nearby, however he also fixes about any other small engine that you can think of.
The tools shown below are just what he works with. Many times he has to fabricate pieces that would be impossible to buy, or to expensive for him to make a profit on. It is really amazing to see him work, and to watch the problem-solving take place. As Bernard shows us in this video and pictures, your imagination and ingenuity are the only things holding you back.
