Although I have not seen one like this (and wish I had one), most "KILL" buttons are red on one side (and say "KILL") and are white on the reverse and say "LEG". It is used in Hold 'em (and maybe other games for all I know) as a marker. Who ever wins a pot also gets the kill button in the "LEG" up position. If the player having the kill button wins a second hand, then the button is turned over ("KILL" side up) and the next hand is played for double the amounts. If the game is 2/4, then a kill hand becomes 4/8. If the game is 10/20, then it becomes 20/40. But only for one hand, unless the player with the kill button wins again. However, subsequent wins do not double the pot again. I may have missed a nuance or two, but that is the basic concept.

Got any traders?
