containers are no challenge apparently. No need to worry about the plastic by-products leaching into your food. A wonderful idea. Someone else in the comments, suggested how convenient this would be if you were traveling and didn't have a knife. What??!! You're traveling and overcome with an irresistible urge for avocado? Oranges? Nibble chips and Cheezies like everyone else. There won't be a huge difference nutritionally.
Yes, I'm of a certain age but I'm pretty spry and like to think still smart enough.
