This goes unnoticed on your keyring so is great for times when you don't want to be seen carrying a full size Leatherman(offices etc). It's a bit awkward to open bottles as there is a blade where you want to put your thumb but you soon get used to this. The only other problem is that when you open it your keys fall off so don't do it over a drain! This is not a problem is you put a finger through the keyring.
