There is a tiny metal cam that drives a very brittle plastic gear on the front of the can opener that drives the removable can opener top. After a couple of years, this plastic gear will BREAK. Hamilton Beach does not carry replacement parts.The whole thing is JUNK once that brittle bit of plastic breaks.Too bad, the whole rest of the can opener is nice and in very servicable condition. I don't think it even opened 100 cans before it broke. If that gear had been brass, it probably would have lasted forever. Now it's landfill.
