Solidify modifier: getting a hard edge?

I’m using SOLIDIFY on a flat ribbon of Faces, but I’d prefer a hard corner at the top of the Solidify extrusion. Here’s a pic:

How does one get a sharp edge there?

It looks like you have smooth shading enabled? Have you tried enabling auto smooth (in the object properties)?

That is the solution I found, but I wondered if there were a setting in Solidify that would more generically make the extrusion/solidification have a hard crease, or better, allow a smoothing angle to be entered by the user.

If you combine it with a subdivision surface modifier, you can change the crease settings in the solidify modifier to change the effect.
