What exactly is the Katana??

[Mrephunk]

I have seen pictures and a couple in the classifieds but don't really know what it is(aside from being a PV) But they are gorgeous. Makes me really want one, just the look alone. But what is it exactly, and how does it work?

It is a rebuildable atomizer with bottom tank big battery PV.

It works like any PV except for the atomizer being rebuildable by the user, the wick drawing from a bottom tank, and the look of it.
