You can wash and reuse cans if you buy this
I LOVE this can opener. It works differently than traditional can openers in that there is no sharp edge. It cuts the lid off of cans in a way that allows you to put the lid of the can back on and keep using the can because there are no sharp edges. I've used this opener for years on many different can types with no issues. I saved the empty can and lid from a few cans of tuna and now I use that empty can to keep my partial cans of cat food the fridge. This works so much better than those plastic lids for cat food. The can closes tightly and I can wash the cans out in the dishwasher. I saved the empty can and lid from tomato juice to keep under my sink for compost. This can approach minimizes any smell. I think it's likely that you'll be, for example, opening up soup cans during power outages, so I think every household should have at least one manual can opener and this is the one to have. It did take me a little time to learn how to use this can opener. I think the first time I used it, I didn't realize the lid had been cut off and I had to lift it off. Once you figure out how to use this, its easy to use.
