Hey folks! So with a huge recent lore focus on drek metallurgy there is going to be maybe a couple more journals and perhaps one or two more drawings about the drek usage of mostly copper and rarely bronze and brass on their toolmaking. This journal is actually an answer I gave to a friend on Discord that I figured I would make a small ramble about. The question was something to the effect of:
"So a lot of technology is lost due to many factors so drekir tend to revert to a semi anachronistic chalcolithic like state of technology. But what if a society of drekir loses or doesn't otherwise understand how to melt and cast copper into molds to make tools, jewelry, etc?"

That I feel is a very reasonable question considering not everyone knows how to cast copper into a mold to make a tool. But that wouldn't proclude drekir from making tools out of the metal. They might instead form their tools through a process that was seen in various regions and times known as Cold Forging.

Cold Forging, or Cold Forming is a process in which copper is shaped without the use of fire and using a limited application of low heat for annealing the metal. Copper is a particularly soft metal that can be easily worked simply by hammering it into the form someone wants and with enough time and effort, one can hammer the tool into the shape they want. Cold forging can be used to make most of the simple tools one might make by casting copper and wouldn't really require the knowledge of casting and pouring molten copper.

A big real world set of examples would be the "North American Old Copper Complex" cultures surrounding the Great Lakes, along with various Inuit cultures including the Central Eskimo copper culture and the Tlingit (who themselves were incredible metalsmiths in many metals) here are some brief links on them

Amongst some other links and whatnot that if folks are curious I can provide.

as for the DragonScape

Copper has been existing in the ruins of the dragonscape for over a century in forms that are relatively easy to coldwork, namely pipes, pins, bars, etc. made of copper, with a pipe being particularly easy to crush into a flat working form. Even if a drek doesn't understand melting and casting copper I could figure it wouldn't be hard for a drek to figure out the copper scrap all around them could be hammered into useful shapes and tools.
All one needs are a couple rocks to serve as makeshift hammers and anvils, then the process is a mix of hammering the copper to harden and shape it, and then annealing the copper to keep the stress created by hammering from cracking and breaking the metal. Then hammering an edge onto it for sharpening before hafting to a tool. A spear might be a section of copper pipe with one half hammered flat and the other half serving as a socket to haft onto a spear. A knife might just be a small copper bar hammered flat, shaped, sharpened and hafted onto a handle. Smaller bolts might be worked into makeshift hooks, etc. These tools might notably look a bit different from the cast copper other cultures might use, generally appearing more oxidized as the hammering and annealing may not remove all of the oxidation present on the scraps. Generally they may not have as "clean" of shapes due to the lack of use of a mold as well. Regardless these copper tools are generally similarly useful to cast copper if not a little less efficient. But for cultures that may not be 100% acquainted with casting and making molds for copper, this would likely be the go to option. The tools are still metal and still pretty good, though arguably less sophisticated than cast copper tools
