I have Thompson 5/8”, 1/2”, and Robust 3/8” bowl gouges. My favorite is my 5/8” Thompson. I use the 1/2” when the 5/8” gets dull. The 3/8” is a U flute I thought I would try, but don’t use it very much. I’ve been thinking about getting a 3/4” V groove, but wonder how many use that size. Is it a good to have gouge?
