Sometimes yes, sometimes no, in my experience. I'm still saying if you want to leave a multi-chain-tool at home, keep up your service stops at bike shops and you'll probably be fine. There are no guarantees of anything. Also, this service stop method is primarily for people who don't know how to use the tools or don't want to get their hands dirty

I carry chain checker with me. When it gets to .75 I start checking my chain daily and plan when I'll be somewhere to pick up a chain. I'm cheap and don't mind dirty hands so I save the $15 or so that a shop charges to put a chain on.
