Yeah this photo is actually several months old at this point and I've just simply kept forgetting to upload it so yeah! Lets talk chipped rocks (ground rocks on their way)
I wanted to mix up from the normal copper tool emphasis and so I have been slowly getting into flintknapping and, while I have little experience in it, that makes it a perfect medium to represent early drek tech industries amongst the 1st generation.

Here is a very simple set of crude flake tools produced by chipping off from a larger node of obsidian, the top two flakes were produced from a thick pane of glass that I had found while doing some field archaeology months ago. They were chipped using a single hammerstone made of granite with the simple goal of chipping off useful flakes to make blades. There were a lot of flakes from the obsidian so I just chose a random assortment and the glass pane produced just two before it shattered into useless, unknappable chunks. The largest of which I would consider a very crude handaxe and the other 5 flakes simple, though VERY sharp blades.

This is generally known as Mode 1 flintknapping and is the most straightforward, you're just trying to make solid flakes for simple blades.

Generally a lot of early groups of 1st gen drekir would awake in places where there either wasn't metal, or there was so little that reliance on both natural and scavenged lithic industries were needed to make basic tools. Materials like flint, agate, chert, obsidian, scavenged glass, ceramics, and essentially anything that can conchoidally fracture were and are used by drekir to make tools. Though as early awakening drekir almost always lack flintknapping skills and are starting this practice from scratch, a lot of early tools are crude Mode 1 tools reminescent of the Oldowan industries or Aecheulian industries of stone toolworking. In societies where chipped/knapped lithic industries are embraced of course you will see further development, most often into various styles of levallois or blade core industries.

I am trying to learn blade core and levallois flintknapping, different from the bifacial styles that people tend to know but we will see how it goes. Even though this photo is months old its been hard to find time to practice more so I haven't improved much.
