This is a pen which is frequently mistaken for a Pennant; this is a mistake which I supported with my page for that pen for about ten years, to my great embarrassment, and which a recent item online elsewhere has put me on the path of revision.
In my own defence, the Saber is effectively just a cartridge version of the Pennant. It can be spotted for what it is by what it lacks. Obviously, there is no lever in the side. Less immediately evident, at least if the cap is on, is the absence of the overfeed (or support) bar across the slit of the point. Otherwise, it is very similar to the Pennant, including the wretched C-Flow plastic feed. The claim of “interchangeable points” made by the Pennant is a little more easily supported by the Saber, since removing the section in a cartridge pen is an easier prospect than in a lever-filler.
