Lezyne are making some fantastic well designed and practical bike tools. I really like their high volume lightweight pump and have just recently got one of their v10 multi-tools.
101g - which is a great weight for a such a tool considering it includes a chain breaker.
The only essential thing that this multi-tool doesn't have is a spoke key (or keys). I'm not sure why Lezyne didn't include one, but it means that you need to bring along a separate spoke key.
