Wooden Centrifugal Puzzle

This is a wooden puzzle.  The two parts lock together and you give it to a friend, asking him to unlock and separate the two parts.  A friend in Germany made this one.  When he handed it to me to solve, I could not until he showed me the secret.  This Instructable will not only show how the puzzle is solved, but will also show how you can make these to give as gifts, especially at Christmas.

I have learned through a link by Make! Magazine that this is called a Duallock Cross Puzzle and it was invented by Nobuyuki Yoshigahara.
