If your ok with not being "abo" - aboriginal tools then look at picking up a starting kit. You want boppers of mixed sizes, an Ishi stick, a handheld pressure flaker and some leather pads, abraders - course & fine...and above all EYE PROTECTION. You really can make so many of the tools yourself without too much fuss but you've got plenty to do with just breaking rock.
Flintknapping is crazy addictive and will make time disappear...you've been warned!
My advice is to grab a basic kit get your rock and look to get heat treating figured out...maybe look for a turkey roaster
Watch youtube videos, get to a knapp-in, and just start breaking lots of rock. The Whittaker book 'Flintknapping', I found really worth while.
