More crafting materials

[Doc Sithicus]

Can we have more crafting materials?

I know that we're dealing with lots of snow but we have access to caves and mines so stone and flint - it served our ancestors for thousands of years, why can't we use them now?
In Neolithic times, people made axes, maces and hammers, arrowheads and spearpoints. Also knives and scapers (lets say scraping process would reduce curing time by 30-50%)  

Ductape - holy ingredient for crafting/McGyvering

Nylon thread - found in fishing huts - for fishing, making snares, heavy-duty stitching.

Nails/screws - building things, also as improvised arrow points.

Cattail leaves - when dried can be used for weaving - baskets & mats.

Old tires - can be used for making boot soles

Steel/copper wire - fixing/building things, also snares/traps

Drying Rack - for drying fish meat, maybe skins/guts - also dried food would last longer

Snares/traps for bigger animals: deer, also wolf and maybe even bear (fresh meat as bait required for predators), prey can be killed or immobilized, also some chance for escape.
