To answer your point about the spring, by having this spring, it prevents the blade from opening in the same way a gravity knife opens. If you could open the blade with a simple flick of the wrist, the knife would fall under the offensive weapons act.This has been discussed before on BB with people suggesting asking the Police, CPS, Senior judges, MP's and even the Home office
such a question about clarifying the law
General consensus was not to stir the pot, since for the moment we still have what we have and they could just as likely for their own agenda start looing at restricting that too.
It is easy to stay within the current legislation - just use the one which measures least
or don't and end up being the case law in question
problem is what you've written is wrong
A folding pocket knife is a knife which folds out and back in again with no locking mechanism, and a holding spring to keep it in a closed position, it must also have a blade length not exceeding 7.62cm (3inch). The easiest example of this would be a traditional Swiss Army knife
we've already established the laws says cutting edge not blade length and there is absolutely nothing in the legislation about a holding spring
a) any knife which has a blade which opens automatically by hand pressure applied to a button, spring or other device in or attached to the handle of the knife, sometimes known as a 'flick knife' or 'flick gun'; or
(b) any knife which has a blade which is released from the handle or sheath thereof by the force of gravity or the application of centrifugal force and which, when released, is locked in place by means of a button, spring, lever, or other device, sometimes known as a 'gravity knife',
The spring I speak of is mentioned in Section 1 of the restriction of offensive weapons act 1959
“(i) A lock knife is NOT a gravity knife. A gravity knife should not be confused with a lock knife. Lock knife means a knife which is similar to a folding pocket knife, in that there is a spring holding the blade closed and it has to be prised open. However, a lock knife has a mechanism which locks the blade in position when fully extended. The blade cannot then be closed without that mechanism being released”
