Tajima Wallpaper Scraper
I came across this product years ago and I can highly recommend it if you are stripping tough wallpapers like painted lining and woodchip etc. You put the snap off blade in on it’s side and secure it with the screws and off you go. You can hack the paper off dry. No need to soak. Amazon are still selling them and Ebay also. You won’t find these in a shop as they are a Japanese import. Such a great tool.
