Vintage Metal Jar Lid Wrench Opens Difficult Jar Lids

This is an older jar opener and its in good used condition. There are some small scratches that appear to be from normal use (see photos) and a little rust (see photos). I would consider the wrench in great working condition. This wrench features marbled bakelite handles which I'm thinking is kind of rare these days. Length of wrench is 9 3/4."
