I don't even know what they're called. About 6" long and 4" deep. Made up of hundreds of thin steel rods in a row. Push it against a corner or molding or whatever and you get the shape of the portrubance you can then trace to a piece of wood. Someone said it might be called a profiler. Anyway, I can't find one anywhere - not Screwfix, not Machine Mart, not Axminster. Not e-bay. Totally blank stare from the guy at B&Q! (He must have been at least 16.)
Anybody help?
Thanx,
