It’s approximately 1” x 1.5” (2cm x 3cm). It came with…:
Tap for spoiler
a bag of macadamia nuts still in their shell. The shells were pre-cracked and the tapered point is used to slip in the crack and twisted to open the the shell the rest of the way
…but I don’t believe it was purpose built for that use and leaves the little hook with the bent tab unexplained and unused.
Lemmy - What is this thing?
It is absolutely made for macadamia nuts.
I agree that the notch is purposeful. I can only assume that it’s just a means of getting leverage for stubborn shells.
A lot of these have those holes too. I’m assuming people hang them up?
