IT appears to be similar to ones offered with shaving soap a few years back. That knot ring means they did take the time to surround the knot with metal which prevents the swelling wet knot from cracking or breaking the handle.
And, yes, they can be great user friendly latherers!
JMO, YMMV

PS. Some of the Omega brushes will let go of the knot if left in too hot water. Their brush structures can be/ are different than most other makes.
