Are all Emerson knives supposed to have a year printed on them? I just purchased a CQC-8 BT W to add to my Emerson collection and after looking it over a few times i realized that it had no year date where my others do. Is it normal to see this sometimes? Number on it is #4058 . Also on this blade the grind comes very close to being a chisel grind which seems weird. The lock side the edge is less than a 1/32 of an inch wide while the other side is around an 1/8 inch. Debating on possibly returning this but first i would like to know if this is defective or just a rare combination of uniqueness. It was missing the sticker that's usually included as well.
