suggested it a while ago, but haven't tried it yet...chopsaw a narrow square notch in the hook end of a Wonderbar for a chain link fence breaker...

a short section of hacksaw blade in your EDC does not take up much room...if you carry a knife with pocket clip with lanyard hole at the same end, a split key ring can connect the saw blade to knife, rotate the saw blade through the pocket clip to make a fairly efficient handle...if lanyard hole is at opposite end from clip you will need a longer piece of blade.... the saw teeth will chew up the scales of your knife though

Channel Lock has a 6 in 1 rescue tool for firefighters you might look at in addition to a pair of fence pliers
