Sorry for late answer.
On the scheme there were a mechanism that could make burial blade work like in game, but we couldnt make it in time.
So blade could be deattached and it was made with use of really strong maghets in handle of the blade and in the scytle handle. Its not that easy to remove it,but in meaning of safity there also a couple of screws.
Also the scytle can be bended in the midle like in the game, cause it made from two separate parts. There is a pin in the midle wich fixates both parts together and it can easely closed/open.
