Bathoom Mixer Tap - Cannot Get the Cap off the Tap

[DIY2014]

Tap drip drip drip.
Trying and failing to get the domed cap off the tap.

Tried turning, can't turn it.
Tried flipping it off with a screw driver, won't budge!
Theres no little hole for a grub screw or allen key either.
Tried twisting the arms, but they won't budge either.

Ive tried to reverse image search to find out who makes these but can't locate anything on line.
I'm stuck!

Try gently tapping a Stanley knife blade in there, and maybe a bit of WD.
Work your way around.

I fixed it!
For folk with the same tap, what I did was get a reciperocal saw and cut a notch into the cap and then use a screw driver to move it and then unscrewed it, the rest was easy.
What a badly designed tap cover, it IS impossible to remove, unless you cut a hole in it to allow it to be pushed ith a screw driver, else no chance!

So the cap is threaded? Seems like a silly design choice.

A suitable sized pair of grips with a thin bit of cloth might have unscrewed it.
Lightly grease it before putting it back.
