  We show how both the ellipticity $\eta$ and degree of polarization
$\textit{P}$ influences the extraordinary optical chirality properties of
non-paraxial vortex beams. We find that, in stark contrast to paraxial optics
and non-vortex modes, extremely rich and tuneable spatial distributions of
optical chirality density can be produced by an optical vortex beam under tight
focussing. We develop a theoretical description of how the optical chirality
can be tailored for purpose by altering both the state $\eta$ and degree of
polarization $\textit{P}$ of the input vortex mode, along with the magnitude
and sign of optical orbital angular momentum via the pseudoscalar topological
charge $\ell$. We expect that the results will have a significant role in both
producing novel techniques and improving existing methods in chiral nano-optics
and structured light photonics.
