Swiss Army Knives
There are a number of genuine "Swiss Army Knives" that are illegal to carry in a public place unless you can show you have a genuine need.
Showing you have a genuine need will either cost you a lot of money in representation fees, or take up your life arguing and agonising about the craziness of the law. Example "genuine need" might be an electric linesman who needs a knife that won't fold back on his fingers. Even so that knife had better be in a toolbox, not casually in a pocket.
Quoting from the
The British Knife Collectors Guild:
What You Can Carry ...
The Criminal Justice Act (1988) says that you may carry a knife with a blade length of 3.0" or less so long as it is capable of folding. That means no fixed blade knives.
That's about as simple as can be - ANY sort of lock or permanent detent mechanism makes it into a fixed blade - Go to Jail. I've seen all sorts of clever attempts to get round that - but nobody has actually taken them to defend in court.
The three inch limit has been challenged in court - and while not setting a precedent - the choil part of the folding blade has not been included in the critical measurement. The three inches is technically interpreted as the "cutting edge". The means that a curved blade such as a
pruning knife could fall foul of the law if carried publicly even if the overall length of the blade was under the limit.
Returning to Swiss Army Knifes, I believe the following would be inadvisable to carry casually in public, or possess outside one's place of residence:
Dual Pro, Forester (including Duals), Nomad Duals, Equestrian, Trailmaster, Hunter, Rescue tool, Picknicker, Outrider, Rucksack, Skipper, Tradesman and Workchamp.
These fail on the simple matter of the locking blade.
From a length of blade these could get you into trouble:
Victorinox Solo, Victorinox Farmer Alox,
I have a Workchamp which is available on my belt, in a pouch and attached to the belt by a short length of paracord. I have modified it by reducing the length of the blade, reshaping the end from a short point to a "tanto" short edge, and critically, removing the plastic locking button from the side scale. This is easy to do by slightly easing away the plastic scale on that side and just letting the button fall free when you have the clearance.
Whilst it pains me to have to muck around with a safe and useful knife in such a way - it does convert it from an instant "nick" to something I'm confident about leaving on my person - whether I'm working in town or on my own on private land.
And to be honest - the loss of less than .5 inch overall length has not really affected what I can do with it.
Another option on reshaping a long pointed blade would be to make something like this:
DoE knife - though I do think that is a spectacularly useless knife given the context. As if you're going to need a Phillips whilst doing the Ten Tors! That can opener looks less than useful too.
Take care out there -
