I don’t take it too seriously. For knives it has to do with the metal quality. You don’t want pot metal knives. For flashlights it has to be L.E.D.S. I really like Olight. For books, it is mostly occult or esoteric if non fiction. For fiction I prefer fantasy and urban fantasy , like the Dresden Files by Jim Butcher.
