I guess you are referring to hang angle. I'm not sure if the saw with the larger teeth is a rip saw, but I suspect it is.
The hang angle could very well be different. I don't see what you are talking about.
Cutting the slot can change the hang angle, and it is difficult to cut exact. It is easy for a tote to turn out a bit different as it is worked. The wood might not co-operate like you expect.
I think Mike did a great job.
