Abstract: The present invention relates to a method of initiating explosive charges by means of splinter bodies (5) directed towards these at high speed by an external explosion. According to the invention, these splinter bodies (5) are given large surfaces or broadsides compared with their own mass and are forced to hit the explosive charge with their broadsides (5?) first in order thereby to transfer sufficient kinetic impulse energy to initiate the explosive charge. The invention also comprises splinter bodies (5) specially configured for the implementation of the said method of initiating explosive-filled bodies (2) and explosive charges (3?), intended for the implementation of the said method and provided with a splinter shell (7) comprising the type of splinter bodies (5) characteristic of the invention.
