I share your interest in this kind of cut. I have also wondered how people are able to do this without it catching. It’s something you see with Ellsworth grinds particularly, which I think is a subtle but necessary factor in why this doesn’t catch.

I think if you asked this turner what he was doing, he’d probably call it a pull cut, and it does have bevel support. Look at the side of the gouge nearest to the camera and you can see that on the sides, the bevel is sloped inward toward the flute. That not only allows but really requires that the flute be pointed toward the workpiece in order for the edge to contact the wood. This is why I think it’s bevel supported.

If we were watching an overhead shot, I think we’d also see that the point of contact is very close to the centerline of the tool. This goes a long way toward keeping the tool from rotating toward the work, and is again related to the way the bevel is ground.

It still looks precarious to me because the cutting edge is nearly perpendicular to the rotation, and watching it, I want to pull the handle down to get more of an angle. I currently use more of a Stuart Batty 40/40 grind on my bowl gouge. The difference in grind definitely affects the technique.

my .02, fwiw
