Some of both, in general I use most things. My truck is worked hard, most of my guns are worked hard. There are however occasional things of extreme value which i "use" by enjoying them, and keeping them in phenomenal condition (Gold plated, hand engraved, ivory, that kind of stuff)
With family heirlooms it can go either way. Some things I know my elders would want me to use, some things i cherish by holding and cleaning.
My thoughs exactly. I use what i buy, but i have a few special items that get extea attention. Like my grandfather's .22 single shot rifle he bought when he was 12 to hunt squirrels. I use it, but only on special occasions. And it gets treated like it cost 5k. Things like knives and trucks get worked hard but taken care of when they get back to home base
