it is definitely an old pre-2014 thingamabob. is a specialised form of a thingy, also sometimes called a wotsit, but more properly a watchamacallit. if it has a doohicky attached to the base of the rabbernacker with a silver moebius nut, it will be worth a lot of money (we do NOT discuss numerical amounts here in public), humongous comes to mind tho. the silver wooden scabbard is likely made from silverwood, a rare tree that excretes a sap made out of raw .999 (with birmingham proof marks) silver amalgam that hardens into decorative patterns. the decorations vary in quality and quantity depending on the age of the silverwood tree. sometimes also used on grips, it has a tendency to fall off in coin shaped patches, exposing the underlying wood. the patches are used as currency by the locals. usually to buy edible moebius nuts which are slightly addictive.
dimensions, weights, colour photos of the unsheathed item and scabbard all will help in further evaluation, closeups of markings also are helpful.
do not confuse the moebius nut with the more common knife nut.
