The law is not about looks and/or feels, it's about facts. As long as the knife obeys the specifications of the law and you have a reason to carry it (even if it's just opening letters or cutting a piece of fruit) and you're not in a non-cutting tools zone (back to obeying the law), there's no reason for not carrying this (or similar).
But that's just me...
I agree, however, a guy I know of (he's a chat mate from another forum) has just been sent to prison for three months. The judge ruled the the exposed part of the knife that was not a blade constituted part of the blade length. He has been given leave to appeal but, of course, that can take 6 months in the UK.
The concern I have is over the extended jumped choil. If our friends in the constabulary are of the opinion that constitutes part of the blade, then is is over the legally proscribed length. I know it's crazy but it seems to be the way things are going.
