Anyone personally seen or used the Mission Critical LDC Dog tag?

Title says it all. It looks pretty interesting and I kind of want it but its like 50 bucks! For 50 bucks it better be able to cut something better than a butter knife! So if you have seen this or know someone who has please let me know what its like. I don't really care if its overpriced if it is in fact sharper than a butter knife.

Thanks!
