Thanks, guys.
Michelangelo, you can bring a fixed blade into the woods. I think the legal limit for a carry is 3.5 inches, but if it is a single hand opener it is illegal unless it is a multi-tool. You can carry bigger but only if it is considered a tool. The Swamp Rat and Scrap Yard I have are not considered tools here since they are weapons. I have a SR Ratchute Mandu which is considered a weapon since it has a double edge and my SY Regulator has been modded into a bayonet, obviously a weapon.
Thanks.
Here in Italy there is not a blade measure that make a knife legal or illegal. What matter is only the context: if you are on the woods, you may carry a 10" blade if you want, but if you are on i.e. a soccer stadium even a 2" blade forlder could be considered illegal.
Otherwise, all the knife with a double edge (a dagger, for example) are considered as a weapons, so you need a special permission to had and carry it out.
