Here in Finland, the law prohibits everything with a blade in public places.
As far as I understand, the law might permit arresting anyone with a Leatherman, but this is not how things work in practice, and multi-tools are worn a lot.
You can carry something if you can present and prove an immediate need for it. An electrician can have his knives, if he's presently at work.
Naturally it's within the law to transport bladed tools around. They can't be readily available (carried) while in transport. If I had to lug knives around, AFAIK the legal way is to wrap them up and keep'em at the bottom of my bag.
So, to sum it up, it's illegal to carry a knife here.
