I have been carry a Kershaw 1605 Clash for several months now as one of my daily carry and grabbing it a bit more lately. Not an expensive knife by any means, basically down right cheap for a solid knife in the $30 range. For me in this price range I am more likely to use as a daily tool and not be as concerned if I damage or lose it. This is a liner-lock, some argue that a liner-lock is less solid than a lock-back, maybe, but I can see the engagement of a liner-lock and on some knives I can adjust, so a liner lock can work for me. Basically the Kershaw 1605 Clash is an economy knife that works for everyday choirs and should work in an ugly and personal situation. The pocket clip can be switched to a tip up carry which I much prefer for drawing and positioning the knife in my hand. There seems to be enough recessed area for the index finger to anchor in to keep the hand from slipping forward when a jab/thrust motion is made and hitting a solid surface. I think many overlook this, there needs to be a tang, index finger recess, or some feature that helps prevent the hand from sliding forward and over the blade when in a fight. One thing that really impresses me on my Kershaw 1605 Clash is the Kershaw Speed-Safe action, mine is so easy and fast, much easier to open than many others in my opinion.
Here are a couple links and reviews.

So basically an inexpensive knife that can do dual duty.
A knife I can use daily as a tool when needed without a concern that I would have with a knife that is $10X more range.
