Spectators are kept in suspense, each time the mentalist uses the palm of his hand, to swiftly flatten three out of four paper cones without stabbing himself with the knife!

The Effect itself

An acrylic glass board is laying on a table on the stage. The mentalist asks a spectator to come on stage to assist him. The mentalist hands him a really sharp boot-knife, along with 4 paper cones. The spectator is requested to stick the handle of the knife, with the sharp blade pointing upwards (towards the ceiling), into one of the 4 slots made on the acrylic glass board laying in front of him. While this is being done, the mentalist has his back turned to the spectator and has no way of knowing in which slot the handle of the knife is in. When done, the spectator is then requested to take the 4 paper cones, turn them upside-down and cover each of the 4 slots with them.

Afterwards the mentalist approaches the spectator, tries to read his mind - WHERE IS THE BOOT KNIFE?

The audience is kept in suspense.

Swiftly and precisely, one after the other, the mentalist flattens 3 of the 4 paper cones with the palm of his bear hand, until only one cone is left standing. Guaranteed the audience is sitting there with bated breath.

The mentalist removes the last remaining intact paper cone. Low and behold, under this intact paper cone is the sharp boot-knife is standing. Nobody gets hurt! 

An ingeniously, non-detectable built-in gimmick certainly indicates exactly under which cone the knife is, whenever the mentalist needs to know it.
