The key may be the increased angle of a thicker blade
I think that the Geldmacher is a wedge or semi-wedge. But I am trying to figure out how the width size of the blade would cause a change in the bevel angle.
That could only be if the increased thickness of the wider blade (if it is thicker) caused the angle of the bevel to be more than the bevel on a less thick narrower blade. In this case you would end up with a more chisel like angle which would last longer but would not cut as easily (theroretically).
This still does not explain the supposed easier shaving of a denser beard with a wider blade. Unless that is the mitigating factor. The increased angle gives you a longer lasting edge after stropping and that gives the better shaving of the courser beard over the entirety of your shave. This would be true because the thicker whiskers would dull the blade faster than finer whiskers, all things being equal. Therefore the edge on the larger angled bevel would hold up better to the thicker whiskers.
So this would explain why a wedge might give a better shave on courser beards than hollow ground razors (theoretically). Comments please.

No pictures this weekend as hunting season starts here in Montana (I almost forgot!) and I will be on my deer stand through most of the time unless I get lucky and then I will be butchering.:)
