Ehrendolch - German Ceremonial Dagger

A German Ehrendolch, or honor dagger, was a ceremonial weapon used by members of the Schutzstaffel (SS) within the Nazi Party in Germany during World War II. Its design drew inspiration from the 16th-century Swiss dagger. 

In Girl in the Glass, Garrett uses Direktor Schmidt’s Ehrendolch for a noble purpose - saving Declan’s life. When Garrett pulls out the short knife with the black handle, sporting the SS symbol and an eagle clutching a swastika, he explains:

“This is Direktor Schmidt’s ceremonial dagger, his Ehrendolch. I can’t think of a better use than saving the professor’s life.”

The 13-inch blade was made of stainless steel and featured a broad, double-edged design. One side was etched with the SS motto "Meine Ehre heißt Treue" (My honour is loyalty) while the other side often included an etching honoring Heinrich Himmler, the leader of the SS. The handle was constructed from black wood with an inlaid Nazi Party eagle and the SS symbol. The blade was accompanied by a black sheath, sometimes attached by a chain decorated with a skull and SS rune plaques. 

The SS Ehrendolch served as a symbol of allegiance to Hitler and was worn with the SS uniform. Production stopped in 1940.
