Stainless Pocket

i bought 2 stain less steel knives both of witch i carry around in my pocket both have rusted any one know how?

i dont live in an overly humid area and i dont sweat THAT much i got stainless steel because a lot of my knives rust after a few days i guess its the moisture in my pocket but its also stain less steel witch i though was rust proof or at rust restaint. 1 week later i see rust? any one know if i got jiped ? and how can i prevent this in the future, preferably while still keeping them in my pocket, looking for a spray or chemical if possible.)
thanks for taking time to read this

Well Moose; Good question. Your knifes are not stainless steel. True stainless steel does not rust. Period. As far as your post goes, try to start each sentence with a capital letter and use proper grammar and punctuation. It will put you head and shoulders above many of the other people on here who butcher up the English Language.
