Is the UKPK is actually legal in the UK?

#1

Post by SpydieCollector »

The title should have been: 'Is the UKPK actually legal in the UK?'

Depending on how you measure the blade of the UKPK, it can be (very slightly) over 3" And who is to say how a police officer will measure it, if you're seen with it in public?

So has anyone got the definitive answer to the UKPK being fully legal in the UK? Or is it a grey area?

Help me before I end up buying a Metropolitan. It's calling to me :zany

The UKPK was designed in collaboration with the folks on the British forum and me to be specifically legal in the UK.

Thank you and I appreciate you clarifying this for me. I'll stand by this definition and use the UKPK as it was intended, to be a UK legal knife.

Kind regards.

I accept the threads are similar, perhaps too similar. Although I didn't find a definitive answer to my UK legal concerns in that particular thread. Now I have, from the knife's designer, and it doesn't get much better than that.

It’s perfectly legal providing the copper doing the measuring isn’t a total w :anchor

This is my main concern. I don't expect every police officer to know everything about the law, it wouldn't be reasonable to expect that. But it is a concern if they measure a legal knife incorrectly and act on that.

But I am going round in circles. I have faith that the UKPK is fully legal now, despite the potential of local coppers believing it's possibly not, and I've never been stopped and search anyway. I just think the police are getting more and more on edge with the state of social decline in the UK, so the chances of random police searches are more imminent imo.

Simple, it's a bladed article with:

(i) a plain cutting edge;
(ii) a sharp pointed end; and
(iii) a blade of over eight inches in length (the length of the blade being the straight-line distance from the top of the handle to the tip of the blade),
which also has one or more of the following features:

(a) a serrated cutting edge (other than a serrated cutting edge of up to two inches next to the handle);
(b) more than one hole in the blade;
(c) spikes;
(d) more than two sharp points in the blade other than:

(1) a sharp point where the angle between the edges which create the point is an angle of at least 90 degrees (where there is a curved edge, the angle will be measured by reference to the tangent of the curve);
(2) a sharp point on the cutting edge of the blade near the handle.

This style of knife had brief popularity a decade ago. The UK government claimed, with little evidence, that these knives were so intimidating that criminal elements preferred their use. Amusingly, the initial ban only included zombie knives that had violent text on the blade, but that loophole was closed recently. Of course you can technically still have a crazy looking knife with all these silly features as long as it's fully serrated with no plain edge. :eye-roll

Sadly this kind of knife is favoured by criminals in the UK, They're used to steal bikes and mopeds off people





It's all over the UK cities. Hence the ban on these knives. And there was amnesty to hand them in. No surprises to say not many knives got handed in.

Holy smokes! That’s horrible! I didn’t know about this! I apologize for making fun. Apparently it’s a very serious problem.😬

No harm done at all with a bit of humour.

Many carry knives in the cities and hide them around where they hang out for quick access so if searched there's nothing on them. It's rife. And sadly not uncommon anymore. Hoodies causing trouble is normal in the city centres.

It is completely legal by the word of the law. Some police officers might give you hard time, but you can explain to them in a calm manner that according to law it is completely legal and you want to speak with their superior. Whatever the conversation might be it's very important for you to be really calm and respectful. Because it will help you to challenge in the court. Hope that helps.

What really should be illegal is to make laws that regulate the physical properties of objects, without a guideline on how to determine these physical properties.

We have a similar issue here in Norway, where they recently introduced a general ban on knives with blade lengths over 25cm. It's a silly ban because if you need a knife above that size you can still legally buy, own and use such knives without any paperwork, so it's basically just a smokescreen to make it appear like our politicians are addressing a tiny knife crime problem related to a very particular part of our largest city, where some gangs supposedly has taken a liking to large knives. It's already illegal to carry these in the city, so yeah.. just stupid.
What it does though, is potentially getting regular, unassuming, well meaning people into a legal squeeze. The law only states a limit of 25cm, with no additional guidelines on how to measure or interpret this limit.
Obviously just setting the limit at exactly 25cm indicates that this wasn't worked out by smart people with proper insight and knowledge on the topic. It seems arbitrarily selected because it was a nice and roundish number and a length that should be sufficient for most people.
Never mind that knives are commonly designed and measured using inches, and that the closest even number in inches is 10" which equals 25.4cm.
Now, that may or may not be just fine. As long as it's stated as 25cm and not 25.0cm, by common math practice, that should actually cover any length up to and including 25.4. But will it? No one knows. Even if, there's not much room for error, that's for sure.
And is it the makers stated length that should be considered or the actual length of the specific sample you received? You can't measure a blade before importing, so who is responsible for production tolerances in this case?
And like with the UKPK, how is blade length measured?

Sorry for the rant, I just get so fed up. The purpose of a rules based society is to facilitate cooperation and competition on even and predictable terms. Not to make criminals out of good people.

With regards to measuring blade length, there's probably no bullet proof way to make a guideline that will have a perfect outcome every time, there's just so many blade shapes, grinds, blade features and handle designs, and someone will no doubt come up with new designs just to utilize some loophole. If we can just accept that and focus on not making criminals out of people with good intentions and make guidelines that are easy to understand and that clearly indicates that any doubt should benefit the accused - you know, these small details that used to separate a free democracy from banana republics and dictatorships.
One step in that direction is to only focus on edged blade length (sure, that's also subject to definition, but still clearly identified on most knives). In my opinion, nothing creates more confusion than where the blade actually starts. Whereas the end/tip is usually more easily identifiable. This will become much less of an issue if any part without a clearly defined edge or swedge is defined as handle.

So basically, if this Izula is considered a 2.63" inch blade length and not 6.25" (which I suspect most people, even police and law makers will agree on):
Image

then this (UKPK) has (and should legally be considered) a 2.58" knife blade too:
