This is an exquisite specimen of a dagger, only a handful of which are known.  Featuring a textbook exterior matching normal specimens produced by E.F. Horster, the heart of this piece is the genuine small rosebud Damascus blade, with a raised gold presentation on each side of the blade.  The Damascus is the work of Carl Wester, as indicated by the tang markings.  Dagger is in near flawless condition, and comes with a detailed certificate of evaluation by Tom Wittmann.  Please read his description, which is more complete than the summary provided here.
