Note that this is for skewed chisels (as used by woodworkers for cleaning out dovetail sockets etc), not skew chisels (as used by woodturners). Skewed chisels (like these ones (https://www.axminstertools.com/kirschen-skewed-chisel-12mm-pair-202373)) have a single bevel at a steep angle and make it much easier to get into the sides of dovetail sockets than straight chisels do.
I was finding it quite awkward sharpening skewed chisels on the Tormek: mounting them in the square edge jig was awkward and the other jigs just didn't seem to suit this sort of chisel very well. To solve that, I made a very simple to use 3D printed jig that seems to work really well. I printed this about a year ago, but I've finally got round to publishing the model so I thought I'd post it here as well in case anyone's interested.

Nice one. This is one thing I don't have.
