In my opinion...
A straight edge means, for me, that the cutting edge are 100% a straight line seen from above. I am now talking very small variations on the edge
A flat edge is flat = plain.
If the edge is not straight, the edge work like a saw, not as a knife.
To get a flat edge both flat and straight are difficult. A edge can be flat - but the edge is not straight.
Chissels edges have often a long flat support for the sharpener. This support give chisseledges a higher quality, they get both flat and straight becouse of this support - when you sharpen by freehand.
If you sharpen both the flat edge on a knife and a chissel edge in a good quality sharpening tool there is no difference between the edges.
