Description : I have a big but really big cutting board for slicing, which is a shame not to use it. It's a little out of date. How to renovate it? It is wooden. It occurred to me to buy emery and osmirkonat it.
Last Answer : Carefully sand the fine sandpaper. Or better yet, at a carpenter or joiner, stretch the board with a planer. If you pull 1 mm from each side, it will be a little weaker, but it will be like new.
