Hi,

It could probably be left sharp.  But maybe 1/4 inch copper tubing 
bent into a circle with a slit on the outside that could be slipped 
over the edge.  Maybe best just to use cattrack or that stuff they 
use on metal edges just for safety.

I suppose the edge could also extend inward flat for about an inch 
too.  Depends on how the roller machine bends it.  If it were like 
1/4 inch thick, then the edge could just be rounded over.

If a shop could make them.  A bunch of raw split shells could 
probably be put one inside the other for shipping.  It is a little 
hard though since it should be a full 1/2 circle as opposed to say 1/3 circle.

I wonder if a strip of mesh or something could be naturally formed or 
flexed into the shape.

Cheers,

        Terry
