Intended as a last ditch tool this printed dagger is more than capable of penetrating soft targets. 4-1/4" overall with a 1-5/8" tapered section.  It is printed from fiberglass reinforced PLA filament.  It comes with a printed sheath with solid retention and cord for neck wear.  It is non-magnetic so it will not set off metal detectors but will not defeat body scanners.
 
The blade section of this does not have sharpened edges.  It is intended for penetrating soft targets.  It is not a utility tool.
