The work of the "Amolador" is a very old profession, that still is possible to cross walking along Lisbon Streets.

Sharpening is an art dedicated to pliers, knives, sewing scissors or pruning shears and other cutting objects, and to the arrange of umbrellas or even pots.

The sharpeners walk along the streets of the city whistling a small harmonica as a call and a notice of their arrival.

Some of the "Amoladores" walk with their old bike, loaded with all kinds of essential tools.

With a tripod they fix the rear wheel to the ground and connect to it a belt, linking the tire to the working table. Riding, the stones used to sharp begin to turn on the stand of their mobile atelier, allowing them to work in any place.
