For the I do not care stuff I have an unsharp Boker Magnum (was ideal for cutting boxes indeed). My normal pocket knife is a Fox Twister, brillaint knife and almost as sharp as a razor off the shelve. The thing is, if they stop you, it will be seen as an offensive weapon and you will be prosecuted (unless it is the old style pen-knife, 1cm wide, 4 cm long, but even that).

Even carrying a screwdriver after working hours will in the major cities be seen as a weapon or a means to break in with (eg cars).

Wouldn't use a knife for selfdefense anyway, the 10KVA twistet electric cable will see off any knife.

And on the Kuuhkri's and stuff, if even in the Netherlands don't even mention them. Theo van Gogh was killed with one and they are disliked, period.

Don't cut yourselves.
