Any weapon hidden in a creative place on a person's body. Not the same as a Victoria's Secret Compartment or Trouser Space. If the weapon is stored around the belt area, the trope you're looking for is Pants-Positive Safety. See also Anatomy Arsenal for implanted variants.

- In Yulia Latynina's Inhuman, the Villain Protagonist hides a gun-like mechanism that fires a diamond bullet in his semi-prosthetic leg when going to assassinate an otherwise Crazy Prepared Evil Prince (this being a distant future where projectile weapons are considered obsolete). It works.
- One episode of Stargate Atlantis has Ronan produce a dozen throwing knives after being strip searched.
John: How many of those do you have?

- The Assassin guild members in Discworld are frequently described as having weapons concealed all over their bodies, to the extreme that, when someone menacing gets near, everyone starts revolving in their clothes.

Later he's visited by Friendly Enemy Rodriguez who he orders searched, turning up knives and pistols hidden in his boots, sleeves, pockets and even in the band on his hat.
- Hidden Weapons specialist Mousse from Ranma ½ keeps an innumerable amount of weapons stored on his person, whether simply tucked away inside his robes (ignoring such little things as bulk, size, and weight of the objects, which neither hinder him nor give themselves away,) snapped into the soles of his shoes, or even a length of cutting wire carefully rolled into the frames of his glasses.
- Before Mousse there was Ryoga. He wore a massive number of bandanna's each one with a razor wire allowing him to throw them like shuriken. His bamboo umbrella weighs several tons and has razor edges, and even his belt can be snapped straight and wielded like a sword. However Ryoga's arsenal was passed over after being overshadowed by Mousse, and he mostly became a straight fist fighter focusing on unusual strength and endurance.
