Creating a knife-edge bail for a pendant

Hi All,

I'm trying to design a knife edge bail for a pendant:



I have 2 versions and each has it's own issues.

In this version, after sweeping 2 triangles along a rail, I get this odd chamfering at the bottom on one side:



In the other version, the sweep doesn't seem to flow smoothly along the curve - it seems to create 2 curves along the edge:



Could someone please troubleshoot this for me?

Many thanks in advance!
