Ok but then arises the question what they consider being a bushcraft knife.
Is it just this british utterly boring model:
Or could this be, too? I think this is buscraft knife.
UK knife law has always been ambiguously worded. We’ve seen this way back with regard to compression locks and button locks where the blade can drop out under gravity. There used to be a problem with customs flicking blades out with a wrist flick and confiscations as gravity knives. I remember a UKPK getting stopped as a gravity knife. Customs were holding the blades and flicking the handles we discovered.
I think it’s deliberate, it allows for confiscation pretty much without question. It’s still a lottery sending knives with RM, always has been.
