I wonder if this would work with a little modifying? Just cut off the rounded part and flatten out all the rows of teeth except the first one. It's aluminum, so with a little hammer and dolly work one might be able to bend it if a curve is needed. In case the link doesn't work, it's a carpet grabber or transition strip used in buildings where a carpeted floor meets a vinyl or tiled floor.
Anyway, here's the Home depot link:

These should be available at any hardware store.
I've never tried this.So it may or may not work.
