yeah I was watching videos of the different ones and wanted the 1/2 and the 1/4 spindle gauge and the other set just has a single 3/8. I get that I will likely end up using a few of these most of the time but I am going to try and make myself use all of them as much as possible the way they are intended and learn to shape and sharpen them all. What I don't want to to is end up using a few to do everything and never even learn about my other options.
You can sharpen the carbide cutters very easy with a credit card size diamond sharpener. They are only around $12.
