Whoever designed this brass dolphin-shaped clip & bottle opener combo was pretty smart! You could hang it from a nail on the wall near the fridge to both hold your grocery list and open a beer when needed, or keep it on the desk to hold papers in order and pop the lid off a cold one when work is done. And in keeping with the dolphin design, I think it would be especially handy on a boat.
4" long by 2" tall by 1 3/4" wide. I have not attempted to polish the clip; its surface shows signs of age and wear, but I think these add to its character. It works great, with a nice tight grip. It bears its original sticker on the underside--made in Taiwan for Nanco Sales Company in Boston, MA.
