If you are hosting your own server, you can enable them.
Code:
UPDATE _RefObjCommon SET Service = 1 WHERE CodeName128 IN (
'ITEM_CH_TBLADE_08_LEGEND',
'ITEM_CH_TBLADE_09_LEGEND',
'ITEM_CH_TBLADE_10_LEGEND',
'ITEM_CH_TBLADE_11_LEGEND',
'ITEM_EU_TSWORD_08_LEGEND',
'ITEM_EU_TSWORD_09_LEGEND',
'ITEM_EU_TSWORD_10_LEGEND',
'ITEM_EU_TSWORD_11_LEGEND')
As far as I know only the glaive and two hand sword exists, by default the bsr files are in the Data.pk2 (so you should NOT need any files to make them work), the 8dg ones were working for sure, I don't remember if I've tested the higher degrees. Don't forget to add it to media.pk2 as well after enabling.
