Funny, I have a Buck 102, that was my first fixed blade as a child. I got it in the early '90s. Unfortunately, my then stepfather was a bafoon of a man, and had me using it to dig in the dirt while metal detecting. It is obviously dull from that digging, but since I never sharpened it, it still has the original edge, and other than some dirt, is in perfect shape. I should clean the dirt off, give it a proper sharpening, and use it as a knife for the first time in its life.
Personally, I'm not a big fan of bowies, but like you, I prefer a slim, balanced blade. Not once in my 28 years camping, backpacking, fishing, or hunting, have I ever needed to use a knife to chop down a 3" diameter tree, stab a hole in a car hood, or pry open my back door.
The chip flint seems nice, but more than 2x the price for a different blade finish?! I would go for the cocobolo if I were you. At least you are getting a nice wood handle and brass hardware out of the deal. From what I can tell, the chip flint is just a woodsman (phenolic/aluminum handle, 420HC blade) with a finish that imitates a worn carbon steel blade, while still being stainless. Doesn't seem worth 2x the price to imitate something you can get for cheaper...
