I'm going to purchase my first RAT soon. It will most likely be an RC-3 or RC-4 (and probably with serrations based on the great comments here about the Rowan-style serrations). I am a first responder so I like the idea of the glass breaker, but I'm wondering if there are any downsides to it. The knife will see first responder duty use but also weekend camping trips with the family and/or scouts. Thanks in advance for your thoughts and advice.
