the second one is used to make punch rugs.
remember the rug yarn in the craft section?
the yarn is threaded through the two holes.
when you push it through the fabric (canvas, burlap, similar) then pull it back out it leaves a yarn loop.
fill in the pattern. presto! pretty rug.
if the first one isn't a tweezers, i don't have a clue what else it could be.
