Ironically, my go to skew is the Richard Raffan signature model, I think from Henry Taylor. Many commercially sold skews have rolled corners, some on all 4 corners and some on just 2 corners. You can easily relieve the corners on a skew with a file and a few minutes time. If you have iron tool rests, rolled corners are essential.
As was mentioned, the tool shown in your photo is almost certainly not a skew. I suspect it's a spear point scraper, but that right edge does give a suggestion of a 'continental' spindle gouge, as Richard said.
