Knife sharpening with a bicycle

I love how everything is so open in Tanzania and Kenya. By open I mean that all the wood-working, welding, bicycle repairs, and tailoring is done on the side of the street for everybody to see. This is a scene which we found particularly interesting. The men are sitting backwards on the bicycles and have elevated the back tire and set up a belt to a grinder. With the spinning grinder, they sharpen knives. What ingenuity! No electricity needed at all. All for 100 Tanzanian shillings and with an exchange rate of 1200 shillings to the Canadian dollar, I think we should have brought the knives from the Silver Bean. Getting through customs may have been difficult though.
