Or are you talking about an additional piece of equipment used in weapons work that I'm unfamiliar with?
Heh! Sorry. Yeah, the scabbard of the sword is 'saya' and in doing batto or iaido, the left hand manipulates the saya during the draw and the return while the right hand wields the weapon. This is saya-biki.
One of the advantages of wearing a hakama for sword work is that, tied properly, the himo and obi together hold the saya securely and provide extra support for the weight of the sword itself.
