Haven't posted lately (been lurking though.... quick look-see each morning before work <img src="/images/graemlins/tongue.gif" alt="" />)
Here is a question that perhaps has not been thought about... it might seem silly or a non-issue at first... but....
If you carry a knife for your EDC, where is it? In your right pocket? Left? Left hip? For the sake of argument let us say you carry it on your right hip and you are right handed.... okay, now put your right hand in your front pocket and pretend your hand is broken, pinned down, missing, whatever... and you need that knife... can you reach it?
The only reason this came to mind was I was working on something where I needed my knife (in my left pocket) but could not let go of what I was holding with my left hand.... I'm not exactly rotund in nature, but it was still a PITA to reach that knife.... especially bent over car grill into the engine compartment. Time to carry two knives! <img src="/images/graemlins/grin.gif" alt="" />
