Do you mean "cheater needles"?
There are two kinds that I know of. One has an S curve as the eye. The other has a double eye with the one at the top end having a slit in it that you "pop" the thread through to get it into the eye. I have the "pop" kind (cause I could not find the S curve kind).
I've used them to bury threads into the batting after quilting and I've never had a problem with them getting caught up in the quilt or the batting. They are indispensable where you have a short amount of thread that prevents you from threading the needle in the conventional manner and still manage to make a stitch.
