I visited a market of folk craftsmanships few weeks ago and this was handiwork of one of the tinkers there.

Tinkers.
Now thats a word I have not heard for years when I was a child they would travel the streets Sharpening all form of tools Repairing holes in kettles,and putting handles back on sauspans.Gosh that was a long time ago. B.C possibly.
