If you’re looking for a discreet and effective self-defense tool, a pocket PU might be just what you need. Follow this step-by-step guide to create your own Pocket PU.

Preparing the Materials

Before you begin assembling your Pocket PU, make sure you have all the necessary materials. You will need:

  • A sturdy piece of plastic or metal
  • Paracord or strong string
  • A small metal ball or marble
  • Duct tape
  • Scissors
  • Lighter

Assembling the Pocket PU

  1. Cut the plastic or metal into a rectangle shape, approximately 4 inches long and 2 inches wide.
  2. Punch a hole at one end of the rectangle and tie one end of the paracord through the hole.
  3. Place the metal ball or marble in the center of the rectangle.
  4. Roll the rectangle around the metal ball, making sure the paracord is wrapped tightly.
  5. Secure the rolled-up rectangle with duct tape, leaving a small loop of paracord sticking out.

Testing and Using the Pocket PU

Once you have assembled your Pocket PU, it’s important to test it out before relying on it for self-defense. Find a safe and open space to practice using your Pocket PU, aiming for a target like a water bottle or cardboard box.

To use the Pocket PU for self-defense, hold the loop of paracord securely in your hand and swing the metal ball towards your target. The weight and momentum of the metal ball can deliver a powerful impact, making it an effective tool for protecting yourself in dangerous situations.
