I've been using the same manual handheld coffee grinder every day for 4 years now, and in that time its rubbery grip has started to fall apart. I've seen folks use a Turk's head knots as grips, so I tried my hand at tying one as a replacement grinder grip. My knotting could be a bit more even, but overall it turned out well and functions great!
