Oh, I remember....
My mom had a Magic Hostess can opener! (with a pretty cool "MH" logo on the front of it...)
Okay, years ago, in Brooklyn, trading stamps were given out in supermarkets as an incentive. "Plaid Stamps" were the big name trading stamps at stores like Bohack, A&P WEO, Daitch Shopwell, and the like.
You'd be handed a strip of these stamps at the checkout with your receipt. My mother would dutifully paste them in her little stamp booklet....when you'd reached a certain target, off we'd go to the "redemption center"....and you'd be rewarded with an exciting new small appliance (the toaster oven that caught fire was particularly exciting, I recall....)
None of the products were from companies that would be recognizable to the average American. "Magic Hostess" was one of those brand names.
Oddly enough, my mother couldn't kill her "Magic Hostess" off! Today's openers pale in comparison in terms of cutter strength and motor, and this can opener was built like a TANK!
It also had the only knife sharpener that I've used on a can opener, to date, that did any type of a decent job sharpening.
