Once you figure out what you like the direction will choose itself. Some folks like a specific brand, some like a specific pattern or style, some like vintage, some like new, etc. I, for example, love Victorinox SAKs and small, single bladed slipjoints. You can be as specialized or as egalitarian as you like.
The beautiful thing about the traditional world (other than the generally high caliber of the people in the community) is that there is no “conventional wisdom” to deal with. For the most part we don’t care about the latest/greatest “supersteel,” stylish new designs, or fancy opening/locking doodads. We do like “pretty,” but we are fully aware that aesthetics lie in eye of the beholder. There is as much beauty in an ancient, well-used knife that has been sharpened within an inch of its life as there is in a brand-spanking new knife made of the finest materials and shaped by the hands of a master.
As such we believe that whatever floats your boat is just fine. I get just as much pleasure out of looking at someone’s collection of beat-up knives that somebody’s grandpa could have picked up at a hardware store for a couple of bucks as I do another’s collection of multi-thousand dollar customs.
You get to do you.
