Okay Dave,

then I have an interesting topic for you that I started on WRF.
SS Christmas dagger did excist for sure. In the provided link you see Himmler wearing an M33 SS dagger with such pointed wings eagle.
Further in the topic you can also see an existing example of a chained SS Christmasdagger. A dagger without inscription on it's blade.
