my initial findings; you could say its a little to big in size not weight for being on a key ring.
and i wonder if the two sided bit will stay in place, riding on my key ring all day at work.
its not to heavy for its size, but feels sturdy enough for some real tasks at just the right thickness
i bought it to be a companion tool to my sidekick and hang from my keys, but if it dont work well there, then i will have to re-evaluate it, carry location wise.
see how it looks , size wise sitting next to my sidekick
