What made me think of this topic was when recently I was helping a good pal in her kitchen and she pulled our her favorite mixing spoon. It was about 15 years old and half the spoon part was burned down to form a slant. It was a realllly cheap plastic, and had burn marks allll over it! But she adored it. LOL!
For me, mine would be the strawberry huller we had when I was a kid. (OK, that would make it AT LEAST 30 years old!!) But hey, that device is all steel, solid wood and is really sturdy! (Hmmm...am I justifying a bit?!?)
