What about locking blades? In Canada these are considered safer but I think England for one has them as illegal?
I could well be wrong but as far as I can see via Google, Ireland and Spain both have very strict carry laws. No knife carry at all except with good reason. Makes the UK seem tame. Malta seems better with an 8cm limit on the blade (no language pertaining to locks in the relevant law?) and it seems that enforcement there is extremely lax. Portugal is a bit harder to find, <10cm seems ok but again I've no idea of the reality on the ground.
Chosing a country to emigrate to, based on what knives I can carry around, is definitely a new approach.
