I closed my Acorn account and still had the metal debit card they sent. So why not try and turn it into a knife. Surprisingly sharp and I believe made from stainless steel as it is not magnetic and too heavy for aluminum so probably a 300 series of stainless. 

I think it goes without saying this thing is sharp and do not treat it as anything other than a somewhat sharp knife.
