A prior attempt to make a trainer out of the V-Gar manrikki was marred as it meant that the rubber-banded foam rubber padding needed to be removed when putting the V-Gar away for storage or carry. This daily assembly and dismantling was a hassle. I have since came across a dead-simple idea using common pipe insulation, made with semi-rigid foam. Just putting a rubber band top and bottom reinforces and tightens the ends of the tube that you insert the weighted end into. It stays. Even when winging the Manrikki around forcefully. Worst case scenario is in the unlikely event it flies off; no harm done. It bounces off whatever it strikes. But so far, mine has not flown off. The padding is sufficient and it is somewhat aerodynamic. It does not add excess weight to the end, so that youre training with the actual feel. When youre done, just slip it off and put everything away. In the event anyone adopts this idea for training, I would advise to still wear body protection regardless.
