A quicky product review.
I got a set of these tools, the mini set, the rougher, the finisher, and the detailer. VERY easy to learn and VERY easy to use. The learning curve to turning has almost disappeared. It is hard to screw up with these tools and they reportedly stay sharp for a very long time. When dull rotate the carbide cutting tip and you have a new cutting surface. When the carbide tip is toast, replace it for about $15~$18. I was told that a tip was good for about 300 pen blanks.
Anyway my other 15 or so tools will collect dust and NO MORE SHARPENING!
