Yesterday I was working at hollowing a small (4" diameter X 2 1/2" high) cherry burl with a 9/16" opening that I eventually ended up increasing to 1" because of the hollowing tools that I have. I can choose either my Sorby small hollowing set with the red handles, or the small John Jordan (3/8" diameter) bent hollowing tools. I know that many folks can work metal and make their own small bent hollowing tools, but I neither have the metal working tools nor the inclination to work with metal. So what is out there for me to choose from that folks have used and liked?
