I think what I got was called “
Bowlsaw”. But it’s been a long time and my memory is not reliable!
Some years back a fellow was making them and part of his plan was to send them out to certain people for feedback.
He sent me one to evaluate, perhaps because I was active on several forums and a moderator on one.

Inexpensive and great for the hobbyist and serious turner, would pay for itself in no time with the wood saved and with minimum sawdaust to clean up.
