Good idea to find a quality source of raw stone/glass near you for a reasonable price (about $1/lb or less depending on stone some are good price for much higher). 1st decide which type of tools you want, i.e. just fire starter, or simple crude cutting instrument or something more sophisticated? Then can you figure out how to heat treat it yourself or is it best to pay for this service or is it even necessary? All I have are questions, I am mostly clueless as well Zack.
Here is a relatively local source for me for just one popular type of "flint". It is SW of Little Rock, AR near the Ouachita National Forest which is a fun place for me to camp and run around like a primitive wannabe. (dry humor).

Anthropological write up at site listed above gives me a migraine, OMG. Hope their stone is better.
There are also several relatively good websites (Not just flea-bay) where craftsmen sell "flint" items and "flint" crafting tools etc but buying in person is always best IMO, such as at a craft fair, outdoors event etc. But even much of this stuff is knives in the style of steel knives but made out of stone, does not make sense to me but I'm sure it sells well. Tourist stuff IMO.
Also not sure where you can find best skilled "Knappers" (spell autocorrector killing me) in your area but, call around, check online, Parks and Rec, Outdoor clubs, Hunting Clubs, Camping Supply stores may offer classes etc. If you can find someone good who is also good at teaching that would be great.
Back to processing wild game: it is easy to nick the inside of hide or outer protective layer of the muscles (ham, shoulder, backstrap etc). Cutting thru the hide even a little is very bad obviously and if you cut into the muscles you lose this outer protective layer and the meat does not freeze or smoke as well. Therefore, I have been told that a "flint" knife properly made in good condition can do this better and stay sharper longer than the very best steel knife. I would like to try one but never have. I have seen video but could not find any good ones on youtube, mostly BS junk there. Just my personal opinion based on very limited experience. However, even a "flint" knife will not stay sharp "forever", even the very best will chip especially if you hit bone, drop it etc. So what good is a knife you don't know how to sharpen properly? Also just my personal opinion based on little knowledge.
If there are not people at this forum who know a heck of a lot more than me then there definitely are at other "outdoor" forums. Hopefully someone here can even sell you a knife and/or "flint" fire starter and tell you how to use and care for it properly.
