Because 99 times out of a hundred you use them to cut through some sort of adhesive packing which gums it up or you are using it for something another tool would be better at but this is what you got and you are doing things to it that would be terrible to do to a high quality knife but you don't care because it's a $30 rip off knife. Also you are always prepared for leaving in your backpack accidentally and having the mother fucking TSA dump out your bottle of kumboucha and steal your fucking knife. I'm all for high quality knives, but for multitasking utility gimmick like this, I'd go cheap every time.
