I was given some Christmas money and thought I would buy a new scraper. I'm just learning to turn bowls so my question is which one to buy? What is your favorite type and size for bowls up to 12". I'm looking at this Benjamin's Best 1" round nose from Penn State. http://www.pennstateind.com/store/LX120.html is there some reason to look at something else and do most of you use more than one?
