I am referring to my Sharpeners on Bicycles post in which I showed a unique age-old process of sharpening knives using the "machinery" fitted on a bicycle. Exactly 23 hours back from this post time, I found him again, the same unique-man! This time, he had his cute little baby boy with him. He has named him Vicky. See the cute ponies in his photograph below. This time, I photographed the full bicycle to show the mechanism.
Full photograph of the bicycle. See how basic yet useful the design is; the rear wheel has an extra ring, which is used to power the rotating sharpener.
Vicky and the unique-man.
