I found this odd thing in my recently departed grandma’s sewing stuff. (Link to pictures below)
It’s about 15 cm, 6 inches long, with a wood handle making up about half that length.
At one end there are two needles. A thick one made of brass or similar, with a deep groove from tip to bottom and two holes, one near the tip and one near the base. Parallel to this, on the side opposite the groove is a slightly shorter, much thinner needle made of steel.
There’s a piece of brass that has holes for the two needles looks like it could be used to prevent the needles going too deep. See images for details.
Anyone know what it is for?
