I don't use it every day, but today I used the pizza cutter that I bought for myself when I was maybe in my early 20s and I thought about how long I've had it. I had been pretty fed up with the cheap ones that my parents had around and decided to spend some money on a good one. I was pretty poor so it's not like made of marble or anything, but it's still sturdy and cuts pizza well after 20 years, so it was probably worth whatever I spent on it.
