Hi Chris
I went to the Sunday Car Boot at Canades de Romero (first turning off on the way to Campasol and about a mile down the road)
There were several stalls selling tools, mostly English. I bought a hand saw, eversharp type for 5 euros, a hack saw full size with blade for 2 euros and several other things. At the Brico in Campasol the other day they had first bay on the right several interesting tools, I bought an 18" level for 2Euros.
Hope this helps
Roy
