Buy another. We realize you probably don't want to give up old faithful, BUT there is one thing that will help. Blacks and very dark colors can be rejuvenated with the magic of mink oil spray. The mink oil will darken the hide, adding color, as well as waterproofing and conditioning. If you spray it on be sure to spray it evenly and on every inch or it will be noticeable where you touched it up. You might get some more life out of old faithful after all!
