Most of the time he arrived with the help of some cart driver who offered to carry his heavy wheelbarrow. That wheelbarrow contained all the ingenuity of the craftsmen of the time. Held by its two projecting handles, the wheelbarrow was pushed along the streets until someone brought scissors and knives to be sharpened. Then, the wheelbarrow was turned upside down, as if by magic, become a workshop.

On the top was a stone wheel, the möla, which was connected by a belt to the wheel of the cart, which in turn was driven by a pedal.

Above it, the knife grinder fixed a tin or a bucket equipped with a tap that would let only a trickle of water fall on the grindstone. Then, pressing on the pedal, he set the large wheel a in continuous, regular motion, while his hands moved the tool to be sharpened from right to left, diagonally to the grindstone, until a silvery finish would form on the blade.

This bronze sculpture, made in 2020, is the work of Campione-born artist Dario Verda.
