I was never attracted to them, and reason more for that is the fact they're illegal to carry in my country. I think they could be useful as EDC though, but... These knives are considered as a weapon here: Switchblades Assisted opening knives Double edged blades and daggers Knives with knuckles or finger holes on the handle (even Karambit) Balisongs Single edged folding knives without a spring are considered as a tool. Single edged fixed blades are also considered as a tool. Also, law is such that it must be concealed, unless you're doing something with it. And your blade can be as long as you can justify the need for such a large blade, and also successfully conceal it. And hardly anyone can justify carrying around a blade larger than 4 inches. Carrying a knife primarily as a self defense weapon is not legal, but it's legal to use a knife in self defense situation, since it's a tool you were pressed into using as a weapon. Same goes for umbrella, screwdriver and other such tools. It's literally dependant on what you're carrying and what you'll say as your reasoning. Laws here are weird, but if you own a small fixed blade or regular non outrageous looking folder police won't bat an eye. Even if they do ask, your reply being "Opening boxes at work" or "Wire stripping, I'm an electrician" and so on, will just make them say "Oh, OK" and return you the knife. However, balisong or spring assisted knife, despite being less dangerous than a similarly sized fixed blade will create you a load of trouble.
