does the cutting hook on the Charge SE blade count?I've never had to use it in an emergency (thankfully), but like you both have said, it comes in handy for plenty of other tasks.
When I'm not at school I have one on the Redpoint Rescue I usually carry, that's the only one I have.
I'd be hesitant to use it in an emergency application as it means exposing the serrated blade on the backside. Could get in the way. That being said, it's better than nothing in a pinch.
I keep a Benchmade 5 Hook in my bag.
