Manual coffee grinder. Didn't see much use lately, but I've used it a lot & that habit isn't going anywhere. Don't need electricity to get a good brew. Pen & paper. And sometimes: pocket calculator. Alcohol stove is my daily driver for cooking food / coffee / tea etc. (Some) paper maps. They always work & rarely need replacement. Nearly antique, hand-powered drill has been useful occasionally.
