Nibs / dip-pens ;-) It's only half a joke: having to regularly dip the pen in ink, be mindful of how much ink you have, having to swiftly wipe it once in a while to avoid drying ink (& flow issues), forces to slow down & take "micro-breaks". This benefits the handwriting, but also the quality of the study. And is surprisingly relaxing. (so called "crow-quill" nibs are relatively cheap, available, carry a fair amount of ink)
