Bali keris holder use

[SidJ]

Hello keris devotees
A quick question. How were Bali keris holders used traditionally? Were they kept outside the house entrance and used to hold the keris of visitors? Or were they used to hold the keris of the householder themselves? Or both? Was it considered impolite to ask a visitor to remove their keris if they came to your house in Bali? Finally is there any source material you can direc t me re the above? Theres lots on keris holders here but not.much in terms of their use within bali culture I can find. Thanks
