Well, I don’t believe that anyone owns the rights to a shaving brush handle shape, lol. BTW, the beehive is the only short-handled brush in use in my place.

The M&F and Rooney beehives were a bit different from others, Paladin Shaving had a blog piece or post on the differences.

Brad Sears makes brush handles in collaboration with Lee Sabini (Morris and Forndran, Rooney) so those would not be considered knockoffs IMHO.

Ken (Paladin Shaving) makes one that’s close but is not IMO an exact copy of the Rooney/M&F.
