What an interesting find! All l can offer is that it appears like something like cording or yarn is meant to wrap around where teeth are, and the pointy end may be used to thread something through a channel of some type, but too large to be for inserting elastic. I wonder if it could be for mending nets? ( fishing, or sports nets).
