[QUOTE=Andrew863;512881]I would assume, by saying relief angle he is refuring to the angle at the bottom of the sear. The one facing away from the shooter.[/Q

I believe Dave stated in the photos that its the Trigger that has the relief angle. " It’s really the TRIGGER which has a relief angle" In the picture, it looks like there is a angle where the safety blade slot starts.

There does look like there's an angle at the bottom of the sear, facing away from the shooter as you mentioned.

I could be wrong. Hopefully Dave will clarify. I like this kind of stuff.
