It rains a lot in the Pacific Northwest, which sucks if you're outside and are trying to write something on paper, as loggers once needed to. So in the 1920s, well before ruggedized tablets were invented, a guy named Jerry Darling created waterproof paper and sold it in notebook form

True to the Rite in the Rain brand, these mechanical clicker pencils are built to be tough, dependable, and refillable. They're made to survive. The knurled-metal grip and one-hand click lead advancement offer glove-friendly handling. The 1.3mm lead won't snap at the tip or break in the shaft, so you can write in a notebook just as easily as it can mark lumber. Simply drop a single lead into the shaft under the eraser cap. Refills for the thick leads and clean erasers are available.
