Caught it
All the kids stands with their weapon in a circle facing the center. The weapon is placed with the grip on the floor, and wit the tip on one right hand finger. On a visual clue, all move tries to catch the weapon to the right before it hits the floor. Anyone not fast enough is out of the game. If everyone caught the weapon, the coach could order all to take one step back, increasing the size of the circle.
