Not quite… just postage of ‘bladed or pointed’ objects to all home addresses… but you can get your kitchen knives (you know the things actually used in knife crime) at your local supermarket, kitchen drawer etc.
Meanwhile there are only one or two “high street” suppliers of foil, epee, sabre, backsword, rapier, longsword, federschwert etc in the whole UK, and the majority are bought online from European smiths, often to custom order.
The ‘carrying’ of any of these for any purpose is currently a crime. It has a legal defence if it is being carried for one of the exempting purposes, but you are guilty until you prove your innocence.
This has been applied in the past to the importation (with all the correct documentation) of custom sharp sabres - the chap was arrested and had a nearly year long battle to have the case dismissed and the £10,000 of his property confiscated returned to him.
The ‘knife crime’ thing is grossly exaggerated too. Something like 5-8% of violent crime includes a knife (somewhat more where there is wounding, of course as a knife is quite efficient at causing wounds compared to… nothing, as guns are hard to come by), and the numbers of deaths amount to a few hundred per year. Wounding seems to be around 3000 or so, but the figures are deliberately obfuscated within the ‘knife crime’ hype, where possession is as serious as use to offend or threaten (with a 4 year mandatory sentence if a defence isn’t permitted).
