Best way to avoid a frown is to deliberately try to make the edge a smiler - an additional benefit of that approach is that the tip and heel of the edge tend to get honed properly.

I've tackled them with tape and bread-knifed them, and I think that tape is better for my mental health. I'm not sure why, but it seems faster (probably all mental).

Like you said, honing a razor focusing on the toe and heel seems to work well for me in avoiding frowns.
