I have a furniture piece made of rosewood (ie, heavy) that has a drop-down
front door. The door fits smoothly into the cabinet face and is hinged at
the door-bottom left and right sides with an unusual recessed hinge. The
hinge is two pieces of brass about 3/4" wide by 1 1/2" long, connected with
a pivot near the ends of the pieces.

Sounds like you're looking for a knife hinge.
