You are bound to see a sharpener on the streets of Mumbai. I’m pretty sure they have their regular spots because I saw this guy in the same place a few different days. These sharpeners are where the city’s knives and blades return from dull edges to well-honed cutting instruments.

The sharpener sits on the seat of a bicycle that has a disengaged rear tire. The gear axle connects to the grinding wheel mounted at the front of the bike by a belt. The sharpener pedals at a pace to match the work, which varies with each blade and throughout the coarse of each sharpening. It reminds me a bit of a powered sewing machine with a variable speed foot pedal.
