Opinions on folders for EDC and general outdoor use Hi there!  I've recently lost my Gerber Evo Jr, and am looking for another knife to replace it.  My budget is $30 max, so I'm trying to find the best value and most versatile knife that I can within that price point.  
I've come across a few different options, and have narrowed down to the Gerber Paraframe I, the Ontario Rat II, and the CKRT Squid.  Ideally I'd like something with a fine edge which doesn't require frequent sharpening, a reliable locking mechanism, and something that has some heft to it.  
Out of those three, which would best fit my needs, and am I missing any great options?
Thanks for the help!
