Just for you to clarify...your email to the police was in regard to the pre-existing situation, or was it prompted in some way by the changes discussed in this thread?
At the 2019 Moot we had a policeman run through scenarios with people carrying knives in packs and the message was that it is situation and person specific. Two people could be sitting with identical knives in identical packs, in the same public place, on their way to the same destination. Both are committing an offence, but only one could have a defence, all based on the route they took to get there. For that reason I rather doubt that you will get as clear an answer as you might like. If they take the time to give varying scenarios, that would be awesome! I just think it very unlikely that they will.
I am not sure that licenses would have the sort of benefit that its sounds like you think they would. You can tell me if I have misunderstood.
- In order to possess a firearm or shotgun, one needs a license. This includes a fee and security inspection. If one agrees that bushcraft knives need to be kept under lock and key, one is suggesting they are somehow more dangerous to the public than the knives in every home's kitchen, which doesn't seem a good idea.
- Quantity and type of firearm and ammunition are part of the license. A similar format for knives would be problematic. How does licensing interact with buying and selling?
- To qualify for a firearm license one has to have a place to use it, and a purpose. This too would be a very bad approach to encourage for knife owner ship, and fairly unworkable I think to police.
- Even if you have a license for a firearm or shotgun, you cannot just wander around in public with one for no reason. It is up to you to prove good reason, same as we already have with knives.
What it seems that most people want when they talk about a license for knives is some kind of pre-check so the police can see what lovely nice responsible people they are, that will allow them to carry knives at times and places where they otherwise should not. Its a get out of jail card.
