the center retainer on the MM should keep it in place. the bent teeth wont be a big deal. I say put a blade in that thing and poke at it with a q-tip to try to see if you can get the blade to move around. It may hold a blade just fine.... or it may not. you really need to put one in it and see.
Although, that really is a poor example of an OCMM and you definetly overpaid for one in that condition. I just bought a cased minty one for $10.00 on the bay and another uncased minty one for $15 BIN.
