sounds - (un-)sheathing ?!

[jlrm365]

I've recently found a nice little addon to handle sheathing / unsheathing of the weapon in a particular hand:

AutoSheath

I had no idea how much - if that weapon is out all the time - it gets sheathed / unsheathed. It happens a lot.

Does any addon exist, to silence such a thing?
I doubt it, given that it's such a specific request, but I have to ask.

Assuming it does not, then...
Does anyone know the various sound files - responsible for the sheathing / unsheathing noises?

I've looked through (but found nothing relevant in):

Mute Annoying WoW Sounds

If I just knew what the sounds are called, I could borrow and rename an empty file.

Thanks!
