Is the belt supposed to be made entirely of metal?

There are really only two hints, the golden paint and clicking sound effects when attaching the grapple gun. Neither really are concrete though. It's never shown off a Batsuit. If it were all solid it would have to have a few hinges behind the capsules, right? All we have to go on is the comic book drawing, which portrays it the way the prop would look draped over the shoulder. Looks like the drawing has over four capsules, and Ordway didn't draw the buckle in half when unbuckled. So that can hardly be considered accurate. I wonder if a special rigid version was made for that shot in the real deal. Then there's that awesome Furst lecture DocDrown posted where he adamantly described its color as "brass" rather than yellow.

What do you guys think or know?
