So my goal was to make a usable tool as quickly as possible with the flintknapping and a friend had helped me get some Mahogany obsidian from Eastern Oregon, I had recieved two pretty big rocks and so I comitted to figuring out how to make a blade core, even if not the best one. I was somewhat successful, took a while and a lot of wasted rock but I did get a core that was able to make some 20 blades eventually, I picked out 6 of the best flakes to show here. I also turned some of the larger flakes and chunks of rock into other tools such as these simple backed knifes.

A blade flake, referring to stone tools, is a flake that is longer than it is wide and they can be made incidently, or from a prepared core which is what I was going for. Sadly the core broke into a bunch of pieces after I overused it so I don't have it here. But these blades can go on to do a lot of things, from being arrowheads to standalone knife blades, amongts other things. I decided to make a knife by carving a wood channel into an old seasoned stick I had sitting around. From there I could glue select obsidian blades into it to serve as a cutting edge and from there I just covered the handle with a shred of walmart bag sitting around, and added some copper wire to add a better stop for the hand. The knife is razor sharp and cuts well even though its still a super crude knife. The advantage of a knife like this is that the blades are easily replaceable, you use hot water to loosen the hide glue within the groove, remove the dull blades and glue in some new blades.
Knives like this would likely be common amongst drekir as flake making lithic industries are the general strategy of drekir. The economic benefits of simply slotting in new flakes both reduces the time of manufacture for stone knives and also makes the handles far more reusable. As drekir begin to develop blade core flake technology to more reliably crank out similarly shaped blades this sort of stone knife would become far more consistent and effective.

Next are the backed knives. A backed knife is simply a larger flake with one end of it dulled so the other sharp edge can be used safely. Backed knives appear throughout human history as a simple but effective style of knife and drekir would no doubt make the same. Pick a large flake with a good edge, dull one side of it to make it safe to grab, throw it away when you're done. The residue on the knife was a banana that I cut open this morning for breakfast (I like to use my blades for cooking, its fun)

Last is the ground slate knife. Groundstone tools are also common in the dragonscape, though as they take forever its hard for me to commit time to making them, particularly with harder stones like Basalt, Quartzite, or Granite. Slate however is a lot faster to grind and is a common material in the DragonScape, both in natural sources and amongst ruins that have things like landscaping slate, slate tiles, etc. In this case this knife started as a slate tile that I broke with a large stone. Then I broke the smaller square with a hammer, breaking off a somewhat thin sheet. After that it was a lot of grinding, polishing, and eventually you wind up with a somewhat sharp blade that is a deceptively good cutter. All I did from there was glue a leather slab to it to make the back a bit more comfortable.

Slate projectile points, spearpoints, knives, harpoons, as well as axes and adzes can and were made out of slate and are made out of slate throughout the dragonscape, particularly as it's a lot easier to avoid mistakes than the fast moving nature of flintknapping and slate tools, from my experience, are sturdier and easier to maintain than knapped stone.

I have more things to show but I want to get some other things done first, things like projectile points of stone, bone, and copper as well as a bone knife I am currently working on. Hope this helps bring to light some drekir industries
