Vintage Kitchen Toll (Can Opener?) With a Red Handle

Something I used to collect a lot was vintage kitchen items. Haven't bought many of late but I thought this one was interesting. Not exactly sure what it is but looks a bit like a can/bottle opener. All these kitchen tools look a bit like torture devices. Looks like it was made by A&J in the United States of America. And on the other side TOOL STEEL TEMPERED. I was collecting red handled pieces but now I think I will go with the sea foam green pieces.
