carring a knife

Why don't you ask your question here:

European Knife Community Forum

You will obviously have to fly neck'd 'cause they won't let you take that on the plane as a carryon.

"Europe" is a continent, not a country.
Weapon laws differ wildly between states and are often quite complicated (e.g. here in Germany it would depend on the length-wide ratio of the blade).
If it's really important for you, I would suggest that you contact the embassies of the countries you visit.

I always buy a swiss army knife when I arrive in Europe. It's a great tool for a variety of uses. I don't carry it on my belt.

Don't you think you can live a week in Europe without your knife. Like they say, get over it.
