i'd use the $100 knife LESS than the $10 counterpart -> that's why i use $1 knifes because i cannot care less if it breaks
even google doesn't use sun blades, that's pretty telling
about home ownership, there are correlations that countries that are low on home ownership level(e.g, swiss) is richer than ones with high level (e.g, spain)
those examples are correlation, not causality ... anomaly i'd say and it's worth practicing
The $100 knife is also usually quite indestructible compared with the $10 counterpart. Even a $100 knife in the poorest care is salvageable with a professional sharpening.
$10 knifes, you can afford to have spares
another example, i no longer use mechanical pencil because it betrayed me so many times (i can't see if there's extra lead inside)
transparent mech pencil is better, but i often forget to bring extra leads :(
that's why i buy 96 counts pencils for $5 ... the lead is visible, it never fails me
and no, i don't bring sharpener (you can always break the pencil and 'sharpen' the lead against rough surfaces)
i bring 5 sharpened pencils instead and put the rest in various places
although it's redundant (to ensure reliability), it's simpler and i'm much happier
But living with 1 $100 knife requires certain behavioral changes. You must take care of it, sharpen it, transport it if you're moving.
Really, these are positive changes and I totally agree that we should be buying more durable goods and maintaining them. In fact, this behavioral change is why the government wants people to own homes. Home ownership gives you something that you need to maintain well rather than simply move away from/discard. It even gives you incentive to improve upon it as that trip to Home Depot can really improve things like the value of the home. People live in communities, improve their homes and communities, and take a real stake in improving things on that local level.
