I think straightshooter is correct, but for old leather that is really hard to use, I give my stuff a coat of Hubbards Shoe Oil to get it so I can move and bend the leather, then follow with a really good coat of wax.

I do not like creaky leather, but, too much oiling and working can turn your leather into a mush that acts more like a pocket than a holster. Too much of anything can spoil a good thing.

You would be surprised at how much leather stuff you find at garage sales and flea markets that can be brought back to use with a little work.
