Mamiya 6: Cutting Replacement Rangefinder Windows

Getting ready for Mamiya 6 rangefinder window replacements this week. I generally cut a small quantity of them for preparation of these repairs.
For some reason, the most often broken window is the Mamiya 6 main viewfinder. While I do see broken Mamiya 7 windows, the broken M6 windows are much more common. Is the Mamiya 6 a more slippery camera that gets dropped?
There are three glass windows on the Mamiya 6: main finder window, frosted frame line window and small rangefinder window.
The second photo shows my cutting jig for the main window. I use 1mm plain glass. The second photo is of the frame line windows and in the foreground is the plain glass that I cut and then grind with 800 grit silicon carbide to produce the frosted window shown in the back.
