Yeah, but does it really prevent knife crimes?

Additionally, it is OK for you, because it might not be of interest to you, but given that the UK is doing all sorts of absurd stuff, what would happen if they did something absurd with regarding to the thing you like?

It likely reduces knife crime. Much as denying sales of lighters and flamable fluids to minors makes fires started by children less likely. (This deeply offended me as an adolescent who enjoyed burning things.)

Is there a benefit to society of allowing minors to buy knives?

We don't have laws to make bad things like murder completely impossible. We do it to make them less likely.

Okay, but not selling knives to kids really reduces knife crime? I wonder by how much, if at all. I am having difficulties believing it does.

Fires though, I can definitely believe it does prevent some arson.

The default is "no ban". You need an argument the other way around. I think it is a silly question by itself. Is there a benefit to society of allowing people to skydive?
