The object is made of thin steel so, yes, it is a bit springy, but does not bend as I think you mean. Those are not crease lines, but are engraved or stamped into it. I really don't know what purpose they serve.
Edit: It seems I am mistaken; it appears to be made of bronze. Not that it will make it easier to identify.
This is good timing. I've been wanting to try this. You'll probably need a wider shot, but here's what I have right now, magnified with a powerful little magnifying glass in my pocket knife.
