Wooden scrapers. Look a bit like a larger version of the little wooden paddles you used to get in a tub of ice cream. My primary use for them is scraping limescale off shower door bits and taps without scratching the chrome. Dried paint splat on glass or tile? Bird poo on windscreen? Has a nice chamfered end for this purpose. Re sand when a bit blunt. My amazingly knowledgeable and practical friend Andy taught me that timber is strong yet soft so an excellent choice for scraping without scratching. Measure 13cm long 3.75 wide and about 4mm thick.
