So i decided to buy a Buck 750 Redpoint 4 days ago with the money i had left over from getting my girlfriends anniversary gift 
But i woke up the next morning and i noticed a bunch of very small rust spots had already formed on the blade. So i just took a pencil eraser to it real quick. Good as new. Then every day since then, when i got home from school, there are just more and more rust spots. The knife hasnt even touched water. so why is this happening? And is there anything i can do to prevent it?
