to knife-jack

to kidnap someone at knife point, then proceed to take them hostage, threaten, rape, or in some cases, kill them.

Nobody knows to this day if Jack the RIpper tried to knife-jack his victims or if he used more subtle forms of psychological manipulation on them before killing them.

if you want to learn how to knife-jack someone, your best bet would be to talk to someone like Jack the Ripper.
