This is what I found...
"Twin Pointed Needles
Twin pointed needles have points on both ends with an eye in the middle. This allows stitching with one hand on each side of a hoop-mounted canvas or quilt. No needle turning means less wrist strain, less thread twisting, less dropping the needle between stitches and faster stitching."
Can be found here....
