I have both the original and smaller Sorby. The "micro" did not come with my favorite wheel, what I call a star pointed wheel, but I think you can buy it as an accessory. The other wheels are mostly made for spiraling which I don't do often. The star is mounted on the largest Sorby in this picture:
The ones I use the most, though, are the two at the bottom which has a star wheel with the points closer together. A machinist made these but they would be easy to make if you can find the wheels.
I like to use them on spindles:
I've made chattering tools but I don't like using them much.
