Putter Shaft Help

[amoline]

Clubfitters and putter experts please help!

A putter I recently got my hands on that I'm very excited about (can post more, and some pictures later!) has a particular shaft that is, apparently, somewhat uncommon.

I know nothing at all about putter shafts, but could someone tell me anything about this at all? -- Supposedly, the shaft in this putter is a "True Temper fluted and stepped stainless steel under black PVD finish" and I pride myself on knowing my golf lingo especially when it comes to the technical stuff that I like, but I am at a total loss here. 

What on earth is a fluted shaft? How does this apply to a putter? Supposedly True Temper no longer makes them, but that may be false. 

Did some digging online about this and that turned up nothing, so maybe I'm just not searching for the right thing. Anyway...

Any help very much appreciated.

A fluted shaft is one with "flutes" in it, like this:

That's all.

if it were not on a putter(not sure they make fluted iron shafts) does it do anything special to the shaft? different weight, flex point?

Yeah, that would be interesting to know. When I get the putter in hand with it and try it out I can report back. Seems to be a feel-related thing, but they seem interesting.

Pretty sure it's just for feel. Steps change the way feel works, too.
