Face it.  The world can be a scary place.

The first 9" to 11" dagger [RazorDagger] that fits the contour of the human body. What would you do with such a thing? If you were, say, out in the North Woods and encountered a bear in heat...or in a really bad part of a really bad town...just the idea of such an accessory could come in handy...especially if this unique engineering feat fit nicely around your mid-section, which this does.
