Thier "warp core" probably holds a Glo-Toob or Glo-Toob FX.

If you need a kubaton that can hold a fractional survival kit, and an area light, sure, it is worth it. Odds are it is excuisitly machined, and it a hand made, limited production item. As a result, not only is it a viable urban and wilderness survial item, it is also an art object- "guy jewlery". "Survivor bling", if you will.

All that said, I think it is over priced. If they got someone to make the origional Life Capsule on a regular, mass production basis, I don't think they'd loose anything in quality, and the price would go down. I could see spending up to about 30 bucks on a no-frills version, but I could never justify this much money.
