The knife-sharpening bicycle

Peter Kahugu of Banana Hill just outside Nairobi makes a living using his bicycle.

And no, he is not a professional cyclist.

AfriGadget reporter Afromusing and I had an opportunity to interview Peter who has modified his bicycle with a belt, a set of tensioning pulleys and a grinding stone to make it a knife-sharpening machine. By kicking the bike up onto its stand and engaging a gearing system, he is able to use “leg-horsepower” to drive a grinding wheel and sharpen knives while “on the move”.

Peter has been at this for 2 years now and he makes about Kshs 500 ( app. 10 US$) a day by riding his mobile workshop from client to client sharpening all their knives as he goes. The grinding stone he uses has lasted an astounding 2 years and he has had to replace his drive belt a couple of times but that is as simple as cutting up a long strip of rubber from an old car or bicycle tire inner tube.

Be sure to click though on the image for video on YouTube of the Peter and his bike in action.
