Query: Rust, Rust, and More Rust

7 months and this baby is ready for the trash. I could accept that from the $1.99 camping can opener. But I'm not gonna pay $12.00 for this thing to rust out in half a year.Problem being the rust builds up on the shaft of the turning gear and slowly works its way through to the divet. We have never put this thing into the washing machine. Very disappointing.As an emergency replacement we got the no name can opener from the grocery store. Cheap, clean, works well.
