Firstly, to people talking about bayonets with a "blood groove": that's a myth and a misnomer. It's called a fuller, and it has noting to do with blood and everything to do with engineering.
Secondly, interesting perspectives here. The fear of knives in the UK seems to have spread to the forum, so that some of us seem to believe that a little Victorinox was designed as an offensive weapon. Or that having a knife is somehow outlandish.
I don't expect that everyone will feel the need to carry a knife, but it's a little blinkered not to understand that a Victorinox Classic, for example, comes in handy several times a day.
To give a different perspective, in Switzerland, Victorinox knives are sold in the supermarkets, often in the kitchen section, and can be bought second hand in charity shops. If you want to buy booze or cigarettes at the supermarket, you will probably have to show your ID, but not to buy an everyday swiss army knife.
And the flea markets often have stands selling all kinds of military surplus, including bayonets. Although I don't think anyone needs to be told that carrying one everywhere is not a good idea.
of course, this may be the most useful of all:
