how many of you carry the cheap liquid filled compases? the kind that they put in the cheap hollow handle survival knives? how many of you knew that the liquid is actually kerosene? a friend had one of thoes cheap knives and started throwing it at his shop wall which was old drywall. he missed and the knife hit sideways knocking off the compass which broke in half. i picked up the clear ball half that held the compass and smelled kerosene. the compass was held in place with a round nut so it could have be removed easily. there was a plug in the plastic ball so destroying the compass wouldnt be necessary to get the kerosene out in an emergency and it could be refilled and reused. i'm not sure if all compases are this way since mineral oil could also be used.
