i think Jimmy and others right about contact the seller and ask for refund.
i bought recently very nice razor and never read the description.
after getting the blade find out it had crack .
went back read the description guess what?
seller mention exact location and size of the crack.
i took lost and leave very nice positive feedback for the seller because of his honesty.
This is not your case. Seller never mentions about the crack and he should be able to accept his item back.
if not then go head leave negative feedback .
