What became of the sword that was used to execute Anne Boleyn?

I don't know what happened to the sword, and in my readings I have not come across any accounts of anyone who claims to know. (So if someone does know, I would be quite interested myself.)

However, for Anne Boleyn's execution, a renowned swordsman from the continent was brought over for the execution. This was seen as a sign of "mercy" for her. It was merciful because he was very skillful at his job, meaning he could sever the head with one motion and therefore minimize pain.

So because it was a private executioner who brought his own sword, my assumption is that the sword would have stayed in his possession and been used for other jobs he was hired for. It likely stayed in his family's possession until it was lost to history.
