I don't think so Claude. They must sell a lot of them.
I almost got one at first and probably would have thought it was great.
Before I rounded the corners of the the shaft per Alan Lacer, the sharp edges used to drive me nuts, gouging my rest in the process.
I have some tools I made which are take offs on Sorby hollowing tools with bits. Theirs have flat shafts. Some of mine are round shafts and some flat. I like them both the same and it generally depends on my mood as to which I use. I guess the key is whatever you feel comfortable with is right. Someday I'll give an oval skew a try.
