12/21/20 - This is an original, pre Luftwaffe "NSFK" DLV Flyer's Knife. This dagger is in excellent condition overall and comes with an original hanger and sheath. The blue stretched leather is excellent and all original. The blade is SMF maker stamped and in minty condition. No signs of sharpening. The only notable flaw we noticed is some very minor chipping in the swastika on the side reverse of the maker stamp. The swastika is located on the pommel. All original and authentic.
