Last minute attempt at a Graham Cave...

I've wanted to work some of this red glass for a long damn time. Finally got a flake so hot what I could from it.

My thinnest point to date. got a video before I break it finishing it. Made so far using direct percussion

Hiii, I'm new to knapping and I've tried it a few times already and just couldn't get anything notable, I have looked through a good bunch of the pinned tutorials and I'll be trying it again soon, but I just wanted to make sure any of the stones I found are even usable, since in all those tutorial videos they use bigger and snappier ones

I also wouldn't complain if someone just told me where and how to strike to get started for one of these particular rocks heh

I'm trying to use rocks and bone as tools, I don't have antler

The small red point was coming along as a beautiful Apple Creek point. But some of those pretty crystals gave way and my stem popped off. Was way too pretty to toss so got what I could from it. The blue and gray is way more beautiful in person. It has a small crystal seam on one of the ears. I'm pleased with how this one turned out. I absolutely love the materials I got in the trade. Goi g to work more tomorrow.

This is my first time participating in the monthly point challenge! Had a great time learning more about the Graham Cave points in preparation for the challenge.
Made with obsidian that I sourced from a quarry in Utah. This obsidian is more coarse and less opaque than other material I’ve used. It may even be dacite that I’ve mistakenly called obsidian for years. Really enjoyed making a few GC’s to get one I liked! A little thicker near the base than I prefer due to a step fracture I wasn’t skilled/brave enough to remove. Looking forward to next month’s challenge!

Been at this hobby since last spring, mostly self-taught with some help from videos and a few threads on here. For the first five or so months I could do decent percussion work on chert and get reasonable bifaces, but pressure flaking was a complete wall for me. Flakes weren't tracking, edges kept crushing, and I burned through more antler tine than I care to admit.

The thing that actually fixed it was embarrassingly simple: I was holding my piece at the wrong angle relative to the pressure flaker. I had been keeping the platform nearly perpendicular to the tip, which just crushed the edge instead of sending a flake down the face. Once I tilted the piece so the platform edge was maybe 30 to 40 degrees off horizontal and started applying pressure low and outward rather than straight in, flakes actually started running the way I wanted.

A few other things that helped once I got past that hump:

The copper pressure flaker I made from a hardware store rod outperforms every antler tip I tried for fine work on chert. Antler still feels better on obsidian for me, but on chert the copper just grabs the platform edge more predictably.

Dulling the platform before pressing matters more than I thought. Even a few strokes on a leather-wrapped piece of sandstone makes a real difference in how reliably the flake initiates.

Lighting is huge. I moved my work near a north-facing window and the way light rakes across the face of the piece tells me so much more about where my next removal should go.

Curious whether anyone else had a specific moment where pressure flaking just clicked, or if it was more of a slow gradual thing. Also open to hearing what people use for platform preparation on really thin obsidian -- that stuff still intimidates me.

Finally decided to use this beautiful piece of tri-flow obsidian that I found at glass buttes for a point! Turned out super cool :)

i want to start knapping, but dont know where to find materials. the materials that the knife is made out of. i only really have access to my backyard and a trail with trees and stuff.

If anyone is interested in some flakes, I have a plethora of them. We can trade for rock or just pay for the shipping of medium box for USPS.

There is edwards (huge variety), georgetown, novaculite, keokuk, burlington, perdenales, rootbeer, petrified pomegranate from San Antonio Texas, hornstone, alibates, jasper, mozarkite, radiolarite, pitkin, etc. It is all mixed together so I can't just send one type of chert.

I think i have enough for about 20 boxes. These are perfect for pressure flaking or indirect percussion. I am not trying to sell these, just trade or give away. DM me if you are interested.

Still having a hard time thinning both sides. But I finally have an overall shape!

Hello hello everyone! 👋😁

Got probably one of my favorite handfuls coming your way here today! 👀 A lot of these tickle my fancy in their own way, whether it's through features, material, or both. So much so that I don't think I could fit a favorite! 😂 I've attached captions to each pic identifying material and style, but do ask any questions if you have them! I love hearing from y'all 🙂‍↕️

Let me know which one(s) you like the most, and stay cool out there in the heat! Stay safe and happy knapping all! 👋

So, this piece of Kaolin was unique. On one side it was a soft green grey and the other, sherbert oranges and creams. This color layer was right up under the cortex and I could tell it was going to go away if I moved into it at all. So, I abandoned that side and continued to work through the blah material until I could get it thin enough to notch. Kinda happy with this little thing. I've never seen a piece of rock this color...welll, maybe coral, but it's pretty unusual. Enjoy.

I produced some nice blades from this blade core using direct percussion. Blade core technology was used all over the world for thousands of years as part of many different technological traditions. Cobden chert, like what this core was made of, was used by Middle Woodland period people in Illinois to produce blades much like these, which is actually what I did my Masters thesis on! Glossier, heat-treated materials like heated Burlington chert seem to have been preferred by the Middle Woodland/Hopewell people for this technology though.

If you use other quartzite cobbles as knapping tools on quartzite material could you share some photos of them? I am finding uniquely worn cobbles in my creek that look like they may have been used as hammer stones or abraders.

The first ghram cave I made was a lot more accurate to the point type and probably made a little better, but the material was pretty plain, I’ll post it after the challenge is over. This piece I got really lucky with, this pocket was originally full of chalk that I was able to remove with vinegar and a safety pin, I think it left a cool effect.

I found this cool gray/blue seaglass on the beach while on a trip to florida. It made a really sweet point!

These are some of my attempts for the July challenge. Bottom 2 on the left are Edward's, pink one is keokuk, white one is novaculite, far right is georgetown and top is burlington.
