I will first say that I am a huge fan of the Leatherman Wave Multi-tool, it has been quite indispensable in my life and travels. Great quality, useful tools, I have used it effectively in conditions where I would've thought only a dedicated tool could have done the job properly.
I would not attempt to discourage anyone from buying this product, but due to my own recent experience I feel I must advise others about UK knife law:
"It is now ILLEGAL to have any sharply pointed or bladed instrument in your possession, in a public place without good reason or lawful authority."
Now pocket knives have their own special category where if the blade is foldable and under 3 inches it's OK but the Leatherman's blades are locking (one of the features that makes them an actual useful tool).
I recently narrowly escaped arrest after a security bag searcher in a public place asked me if I had any sharp objects on my possession. I immediately showed them my Leatherman Wave expecting to have to hand it into the information desk and retrieve it later, which would be an inconvenience as I had it with me for a purpose - as minor as it sounds I was going to use it at this time as a pencil sharpener, as I was at said public place to sketch for my studies. The multi-tool was confiscated, the police were called, and I was told my Wave would be destroyed and, since it was a locking blade possession out of the home, was illegal in itself. My reason for using it was valid, honest, and I was a bit ignorant of the law to be honest as my record is squeaky clean, but I narrowly escaped an official recorded warning thanks to police discretion.
I hope that this informs others who might, like me, want to generally have something as useful as this on them without a definite, provable, work-related reason for carrying it.
