Nathan, I have both sizes and have used them. They are fine for what they were designed to do and not much else. their function is to make that last pass or two on the inside of the bowl. They take off whisper thin curlies and leave a very smooth surface. supposed to be a really simply tool to use, but I feel like it has a pretty good learning curve. Most folks I know that have used it have since returned it or made something else out of it. Not quite sure why I didn't return mine to Woodcraft while I still could. I'll make something out of them one day though.
Working flat so I can play round,
