I have posted the photo of the CW waveform out of my handbook to head off
any potential misunderstanding. I think at some point the ARRL probably
started using a different photo. This one I have posted out of the 1975
ARRL Radio Amateur's Handbook meets all of Tom's criteria:

The accompanying text claims it has 5ms rise time, and you can plainly see
the rounded corners, er, I think? Tom, am I misinterpreting this photo?
