to me, they are very useful. i carry one on my key ring and probably use it a few times a week. anything that i would use my knife tip to pry, i use one of these instead. i mean i had one of my buddies that wanted to use my sebbie to try and pry something apart, i let him use one of these instead. i use it quite often to open bottles, pull staples and nails, scrape stuff, ive used these many of times.
