Gear knob removal

[S B C]

I'm almost embarrassed to ask this question!
How do I remove the gear knob ball? It looks like it should just unscrew, but I can't shift it.
Is there a hidden grub screw or something that I'm missing?

I need to take it off to replace the gaiter. Cheers.

Yes it just unscrews. It can be very tight and I think it has thread lock on it. Might be worth trying a oil filter belt spanner?

Swapped my Gear knob out yesterday for a round momo carbon knob, as said it unscrews, but it is proper stiff, I used a ratchet oil filter strap and a breaker bar to get going, even then it was stiff the whole way..
