The blades themselves are very stable and well-welded to the arm piece; maybe they can even raise (Ausporbieren but I will not).
The bone ornaments can be unscrewed, as the bracelet.
From the little mistakes I've been able to find anything.
Minimum shortcoming:
It is clearly intended for the right hand.
With a steady hand and a knife can be the black finger bone but detach from the white decoration and with a little glue stick new fingers.
So if along the lines of "Why buy just one when you can have double the money for the two" acts could for shootings, film productions or RPG also bear on both sides.
