Wine,
The teeth ought to be filed crosscut. There is usually little set, because the blade is typically tapered pretty strongly from teeth to back.
The high-low tooth shape I believe comes from the blade being filed all from one side at some point.

Hi Wineman ,
Are you asking what type of tooth shape you have or how the teeth were cut originally or how to sharpen ?
Get out your metal file maybe a small triangle shaped one and follow the existing angles and kiss each tooth a few times until the tooth looks smooth and clean or bright .

The tooth set should be appropriate for the curves it will cut. Despite the taper grinding, the teeth will still need X amount of set for how you use the saw. The good news is you can alsways increase the set, so go light at first and set heavier if needed later.
The idea is to use an area nearer the tip for tighter radii cuts. If the radii is really low and if there is a close enough distance from an edge, a bow saw like those at TFWW are a better choice. But a keyhole saw is a handy bugger for long, sweeping curves and moderately tight radii.
I sharpen mine with less rake and fleam. Still a cross cut, but better for longer arcs when ripping.
Take care, Mike
