How to Identify Good Rocks for Flintknapping Arrowheads

This video shows what to look for when hunting for good rocks to flintknap into arrowheads and other stone tools. Not all areas have good rock, so do some research and put some time in looking around. For those that would like to purchase good rocks that are heat treated and ready to knap, you can find them at gillsprimitive...

Maybe it's where I live but I can go to any river or stream bed, or road cut and find it everywhere. I do live directly at the bottom of the Edward's plateu drainage though. But those people pay for the land, they should have the right to keep it. You will find if you ask nicely, even offer to pay, most land owners are amenable to you clearing rocks from their land lol.

I know this is old video, but the dumbest questions are the ones not asked! With that being said. I'm not into napping (other then the kind on my couch) "yet", but sounds interesting to try! I have acquired a source for big chunks of soda bottle glass from where the bottles are made. Some weigh up to 1-2 #s. I got them for the blue green color. Would this make good napping material? BTW I enjoy the videos!

There is no good knapping rock local to me, natives here used petrified wood. Its so incredibly hard to work with, I have immense respect for the people who made the petrified wood points ive found.

[@benthere8051]

Here in north-central Texas, we have a lot of high-quality chert. The outside of the rock is generally yellow with a dark to translucent crystal interior. The flaws in the crystal are infrequent with many rocks producing more than enough flawless crystal to make a good point.

Hey Ryan, I just wanted to say thanks for making these videos. My dad and grandpa were very knowledgeable on these subjects with my grandpa even having a large exhibit of native artifacts donated to a museum. Anyways, I regret not asking them to teach me how to knap stones and make bows, etc. They are both passed now so I will never be able to learn from them, but it offers some comfort that I can learn from you.

[@rmt3589]

Thank you for this. Worldbuilding/game designing, and this helps a ton. Also, I noticed a lot of these are the same rocks that don't require transition metals in their formation. This is perfect, because I'm designing a world without "combat metals", and this allows me to create flintknapping without adding sources of metals such as aluminum and iron!

[@vandalianproductions]

How’s your progress?

[@rmt3589]

@@vandalianproductions Actually have a solid concept of progression of technologies for this world. A lot of stuff ends up being plastics and petroleum-based products. Age of Magic and Age of Plastic replace the Bronze Age, but postponed. A lot of "technology" like concrete, aqueducts, and things made from mineral construction are a lot "earlier" in the timeline, as is boating and woodworks. But that's because it takes longer to harness magic and plastics than it did bronze.

I live in the Flinthills of central US. The rock is usually a dark grey with little circular spots throughout. Most of the arrowheads I've found are a creamy white or pink. I find very few grey ones. Once I found an obsidian which shows just how far they traded.

[@travelinalaskan]

To put into perspective your comment on the trading napable rock. I live on an island off the coast of Alaska in the Pacific ocean with no chert or napable rock. My island is made of shale yet there are napped chert artifacts here. The ancestors of my island would kayak more than 30 miles one way on open ocean in the Shelikoff strait to trade and obtain resources(this does not include the many miles it takes just to get out of the bays where they lived). I have also been told obsidian artifacts have been found in New York, the material for which was quarried in Central Oregon.

I believe many arrows and spears were simple sharpened wooden shafts hardened over the flame. I have shot wood pointed arrows into a dead pig and they penetrated surprisingly deep. Love your channel, just found it last week, subscribed and been bing watching! Thank you!

[@Ironpine27]

A well sharpened stick does penetrate deep indeed since they're so thin and aerodynamic, but a broader cutting head will almost always kill faster with the same hit, reducing the chances of your prey running away so far you can't find them. With a sharp stick that essentially blocks it's own wound too, it's gonna be hard to track down your prey with such a small blood trail.

[@jpthepug3126]

@@Ironpine27 wouldn’t just splitting the head into more heads increase the amount of blood or you could make the tip break off easily and that would allow more blood to flow out

[@Ironpine27]

@@jpthepug3126 Yes, there were in fact spears and atlats with detachable heads, although mostly to preserve the head instead of breaking the entire thing if the shaft is broken. Now making multiple heads is an interesting idea, but it would split the energy between each head, reducing penetration drastically. This is why multi-pronged heads are often seen on fishing spears, and small game arrows, but pretty much never on arrows and spears intended for bigger game.

I know the pain. I used to live in Wilmington, NC and there was no natural sources of knappable rock. Until I found out that the trading ships used to use flint as ballast.

@Charles Millson You would need to walk both sides of the river bank between Wilmington and South Port. I walked on the buffer zone near Carolina Beach but that was before the military closed off access to the public. There is also rhyolite in the Asheboro area. There are several people that sell it online. But rhyolite is extremely tough and not very easy to knap compared to flint or obsidian. Hope this helps.

thank you so much, man. just discovered your channel and website, this is awesome resources! inspired me to learn a new skill - i'm heading out right now to scout an area and hopefully find some rocks. will update back here soon

[@aquaexnar3093]

wow. let me just say, that was a lot easier than i expected! i grabbed my longboard, bought some supplies and traversed to the nearby river i live close to. everything was coated in a layer of dirt, so i only had the texture of the rock to go by, the color of everything was the same dusty brown/grey. despite this, within less than 5 minutes i had found a softer, sparkly quarty red rock that split nicely despite feeling grainy and was holding my first knapped piece. i continued to practice knocking pieces off my host rock and just getting used to the motions. i had found some driftwood and set up a bench along a larger volcanic rock, cleared a small area and made a sand pit so any shards that fell/shot off could be retrieved. eventually, the rock i was using (just a common black river rock here) to knap broke and held somewhat similiar edges, so i grabbed another and started knapping this one. it broke like expected, but into much larger, unusable pieces. the rock was too brittle to be worked. nothing like the clean flakes from the first one. inspired by this however, i went on the search again, and found another black river rock, the same like as the one i was working a second ago, except muuuuch darker and really smooth. this one was harder to work because it was so small, and i found that it really helps when you're not using a huge knapping rock! size doesn't really matter, it's just the angle and force of which it makes contact w/ the rock. after downgrading to a smaller knapping rock, i managed to start chipping off the harder rounded exterior of this black river stone and producing sizable flakes, and these blew me away! by far the sharpest flakes i had produced so far, and none of these rocks were even close to as glassy as the ones you had demonstrated in this video, but still had a SHARP cutting edge! i was playing with one of these black pieces and managed to slice my thumb hahaha. all in all, a good experience and i thank you! i saved a collection of usable pieces and the host rocks. i'm excited to learn how i can work these further.

This was really fun to watch! I am not into primitive hunting yet, but I used to be really into hunting for native American artifacts when I lived in Georgia.

Second: Is Kettle point Chert from the southeastern shore of Lake Huron in canada. Third source: Is Bayport Chert from Saginaw bay area of Lake huron. Bayport Chert is roughly 120 miles from were i find artifacts of it. Those indians would have paddled canoes 10-12 miles out to the Charity Islands to collect Bayport chert. These islands are made of limestone and the chert was found weathered out in the water. Diving without scuba gear to get it.

I know this video is old, but I have two quick questions. Hopefully you'll see this. Is there any specific way to make the first break on a rock? Something similar to needing a good shelf to flake? Secondly, I have several century old glass dump sites, and I've seen videos of guys knapping glass jar and bottle bottoms, which they recommend for cheap easy practice. Is that something you have any feelings about one way or the other, and would the techniques be the same (I'm assuming so)?
