My experience with knives, art, collectibles of any kind - has been that it takes several years to start developing an eye and awareness of what is truly worthy of your attention. Your specific interests are likely to develop, evolve over time and so you might start out favoring titanium tactical and later find yourself focusing only on stag handles traditional - folders or fixed blades. My point? Be patient - study - buy and sell and realize that you are on shifting sands - but have fun.
As to where to begin - here on BF there are many exceptional custom knife makers. Spend lots of time reading the "
Custom and Handmade Knives" forum and checking out the exchange -
The KnifeMaker's Market and the
Custom Knives (Individual) forums. Pick a style or two that you like (today) and focus on the knife maker's that seem to make in that style. Know that there are thousands of
beautiful knives 
but in time your definition of beauty will become more refined. When you start paying attention to the nuances of details, edge profiles, blade &/or handle materials, finishes etc. that are available and that EFFECT the way the knife handles and works you will know what I mean. Not all beautiful knives are created equal. Lots of shallow beauty out there.
Buy some knives - sell them on the exchange. Don't expect to make profit. S&H and other fees and serious competition make catch and release of knives a non profit mission. There are some pretty awesome custom knife vendors out on the world wide webs. Do some research, watch videos.
Again - be patient - enjoy. Good luck. Don't forget to share the fun. Write and give feedback especially for the maker's who impress you. We are looking forwards to hearing more from you. :thumbup:
