What kind of hoops do you need to jump through to own such knives in GB?
In a nutshell, it's illegal to sell knives (or import them) if they are:
1. Designed specifically to look like something else and be concealable in that design (e.g. a walking stick sword/comb knife)
2. Designed for no legitimate purpose other than use as an offensive weapon (push daggers, knuckle duster knives, stiletto daggers e.t.c. The Argonne assualt would also no doubt fit this catagory)
3. Any knife that opens/reveals it's blade by way of an actuated mechanism (flick, automatic, or gravity knives including balisongs)
It is not Illegal to buy or own these knives however, as they are often old and are collected as legitimate antiques, or they are kept by museums, etc.
It is, however, illegal to carry or use in a public place ANY bladed object with a cutting edge exceeding 7 centimetres (3 inches) without a legitimate reason for doing so. In fact, even if the blade is less than 7 centimetres long, it may still be considered an offensive weapon depending on use/context etc. Where knives specifically are concerned, NO fixed blade or folding knives that lock in the open position can be carried even if the blade is less than 7 centimetres long. What that effectively means is that the only knife you can carry in public and not risk arrest is a Swiss army knife or similar.
So for me, if i'm driving in the car and the police stop me, and for some reason happen to search the car and find my TGLB in the boot, I better be able to prove I am on my way to a camping trip or something, or I will be arrested immediately. Same goes for if I carried it in a backpack while out shopping in town. And forget about actually wearing it on your belt while doing ANYTHING other than what it is immediately required for.
But if a copper walked up to me in the woods while I was practising some bushcraft or something with it, he would just be like, 'wow, that's a lovely knife. Enjoy your camping trip.'
British cops are weird.
Anyway, shipping update: I got an email from USPS that my TGLB has cleared customs...won't be long now!!!
