This ultra-slim, ultra-light little neck knife is designed for ease of carry so it'll constantly be with you.  The great thing about neck knives is that no matter what you're wearing, your knife's always there.  Some knives don't fit in your pocket, some are too heavy or don't conceal well.  But the Luna can stay with you no matter what.  The mill-textured integral handle is confortable to use, yet keeps the whole package super-thin, so there's no lump under your shirt.  The "HT" finish is simply the natural color taken on by the knife during heat treat.  As a result each of the HT models is unique -- resembling, but not exactly the same as the knife in the photos.  Length: 4.5 inches.  Steel:  S35VN.  Weight is a feather-light sub-1 oz!  Comes with a kydex sheath.
