Neck knives are favored by those
who are legally restricted from carrying larger
blades, or who are prohibited from carrying a
concealed fixed-blade. A Neck knife is a small
fixed-blade knife which is carried by means of a
"pendant rig", in which the knife is suspended from
around one's neck, handle down, by either a length
of paracord or, more commonly, a breakaway beaded or
ball chain such as those utilized for military dog
tags.
The knife stays in place by means of a form-fitting
synthetic sheath, which holds it securely in place
until yanked sharply. Some manufacturers prefer a
looser fitting sheath augmented with magnets.
