one of these "diamond" tool holders from Eccentric Engineering. Great design, and so simple to use and sharpen. I've been impressed with it. I wish they made them a bit larger, even their largest one is kind of small on a good sized lathe, but still works like a champ.

no tool can handle every situation, but it's on my tool post more than 1/2 the time now. they do make a left and right hand version, up close to the tail stock you might need to switch to the left hand holderSuch an insanely good and simple product. It's so quick and easy to sharpen hss tooling. The only downside is that I may never never actually learn how to hand sharpen hss to other geometries.
I guess if I had to nitpick, I've also encountered situations where I'm cutting really close to the tailstock where the holder can conflict and it might not with a more traditional holder. That said, I could probably fudge the stick out a bit more.
An excellent buy in any case.
