When the defendant has been held to answer the charge the judge shall cause each of the material witnesses on behalf of the Commonwealth and, at the defendant’s request, each of such witnesses for the defendant as the defendant may suggest, to enter into a recognizance before the judge to the effect that the witness will attend and testify in the court to which the defendant has been held to answer, or forfeit a sum not less than one hundred dollars ($100) to the Commonwealth of Kentucky. If witnesses for the defendant are recognized, it shall be so stated in the recognizance.
