Our Nightshade knives are light enough to be tied, tucked, or taped just about anywhere on one's person. And, since they are impervious to heat, cold, moisture and extreme weather they are a natural to hide both inside and outside your house. They can be hidden virtually everywhere from the hedges and flowerpots in your yard, to the refrigerator, bookshelves, and closets in your house. Keep one in every room of the house, from the laundry room to the bathroom shower! With violent home invasions on the rise a strategically placed Nightshade could save the day, and even your life.
