Morakniv Eldris Neck Knife
I'll pass on a knifed neck, but a neck knife? That I will take under consideration. The Morakniv Eldris is a 2.2" 12c27 stainless steel fixed blade, won a "2016 Scandinavian outdoor award" for its functionality, quality, and design. I'm not sure about the specifics of this award, or how many fixed blade neck knives there are in Scandinavia that could have competed against it, but the Eldris is compact, slick, and pretty cheap, plus gets a lot of favorable reviews, so I'll give the vagaries of the award mention the benefit of the doubt.
Morakniv made the Eldris to get down and dirty with a super sharp blade and super rigid, durable TPE-coated polypropylene handle. The knife's spine blade can also be used as a striker with fire steel. It comes inside a plastic sheath of black, blue, green, red, or yellow to match the handle color, and measures 5.6" in total length.
