Query: Pathetic piece of plastic junk

To the folks who manufacture can openers. Please look back 50 years. The last can opener I had lasted that long.This one was used once, the mechanism jammed as it was grinding metal shavings from the can, and into the food.Tossed the food and this can opener in the trash. Not deserving of one star.
