Not exactly sure . I had remembered as a kid seeing a picture in a book of some indigenous people doing a sort of stick and poke tattoo with a sharpened needle and string wrapped around the end as an inkwell (I'm guessing) and I thought it was necessary at the time.

The tattoo only says IFX these days as I wasn't pounding the protractor in far enough. Which everyone knows gets you nowhere , ya gotta pound things in
