Cable lock

A cable lock (10), comprising:

• a cable (16), for locking an object thereby;
• a first peripheral electric conductor (54B), surrounding said cable (16);
• a peripheral insulating layer (22), surrounding said first peripheral electric conductor (54B);
• a second peripheral electric conductor (54A), surrounding said peripheral insulating layer (22);
• and
• an electrical circuit (62), for alerting (56) once any region (58A) of said second peripheral electric conductor (54A) electrically contacts an adjacent region (14A) of said first peripheral electric conductor (54B), by crossing said peripheral insulating layer (22),
• thereby a blade (28), pressing on said second peripheral electric conductor (54A) induces said electrical contact of said second peripheral electric conductor (54A) with said first peripheral electric conductor (54B), for inducing said alerting (56),
• thereby said alerting, induced by said blade (28) is triggered prior to cutting said cable (16) by said blade (28), whereas another object (44) being broader than said blade (28), pressing on said second peripheral electric conductor (54A) does not induce said alerting (56).
