This refers to my recent posting about a 'chipper' type tool as used by welders for removing rust. I wanted a small/lightweight one for removing rust from our boat hull and superstructure.
Well I've bought one of these:-
It arrived today and, after a short play, it seems almost *exactly* what I wanted. I doubt if it's particularly good for removing paint from soft[ish] surfaces like wood and plastic as it is rather easy to dig in the to surface being scraped. However for scraping corrosion and old paint off metal it's excellent. One of the blades is quite narrow, about 1/2" wide, and will be good at getting into awkward corners on the boat.
I've also found that it's rather good at scraping lime-scale off horse waterers! :-)
