Poking Hawaiian seashells for Niihau shell jewelry can be very frustrating and painful when you use the wrong tool! Momi shells are commonly used in Niihau shell jewelry. Momi shells have thicker shells, so they are much harder to poke. Many, perhaps most, people try to do this with a needle. I have no idea how many shells I've poked...maybe a million? I don't know, but I do know using a needle is as painful as it is frustrating. Don't forget, the hole has to be positioned perfectly to create heirloom quality jewelry. Whether being used for Momi, Kahelelani or Laiki shells, this poking tool is a lifesaver. You'll break many less shells and that in itself makes this tool worth its weight in gold.
