I have an alox pioneer in need of some help. It was of the very first knives I started to carry on a daily basis and it was also the knife I had on me the day I got married. Anyways, there seems to be a problem with the blade back-spring. It is really stiff, and no amount of lubrication or cleaning seems to make it "springy" again. All the other tools in the knife snap when opening and closing but the blade only snaps when closing. I used to able to open it using only the nail nick but now I have to pinch the blade and really put some effort into opening it. Any solutions that I anyone can recommend?
