I bought this Sorby spindlemaster a couple of years ago but never really gave it much of a try. Now that I'm retired, I have more time, so I gave it another try. I must say, this may be my new goto pen turning tool. In the past, I was trying to use the tip, making it very hard to control. I watched a few videos and found out the correct cutting edge is on the sides. Huge improvement, easy to control and it leaves a tool mark free surface. It's very simple to sharpen, as you only hone the flat side. The picture of the piece in the lathe, is straight from the tool, absolutely no sanding. The one I have is the micro size. Cutting edge is about 1/2 inch and the overall tool length is 10 inches. They make different sizes. I'm glad I gave it another shot.
