Things You'll Need
Instructions
Purchase a hollow plastic or cardboard cylinder. You can buy one from any major home goods or hardware store. Before you purchase it try to put your arm through it. Make sure that it covers the area from your elbow to your wrist. Make sure that it fits comfortably.
Purchase a plastic blade or knife. Make sure the blade is composed of a plastic material to avoid risk of injuring yourself or someone else.
Attach the blade to the edge of the hollow cylinder and fasten it using tape. Use multiple layers of tape so that the blade does not loosen or fall. This will represent the main piece of your blade.
Wear the cylinder again and make sure it fits comfortably. It should not go beyond your elbow because this can make it difficult to move or bend your elbow. Rotate the cylinder so that the blade is positioned directly behind your wrist. This will mimic the blade from the video game.
