Yeah Question on what is rare

[onoshi]

I hear there are some Magatama you can't craft or find recipe you can only find them as a drop like Pineapple magatama I was wondering if anyone had a list of all of them? like the magatama and then if that magatama is dropped as a recipe or not. I recently found a Gedatsu magatama which adds Rank5+ Axe skill force+47% and I am not sure how rare it is for selling it as I do not use axe
