Ok so I planned an embark where I would have everything I would need to set up a steel industry, and be able to do so by just past the start of autumn. I did this in the master work mod, which has blast furnaces so smelting the steel was a easier, but even without the mod it wouldn't be too hard to set up a steel industry before the first caravan. I had brought a proficient weapon smith with me so he cranked out so steel serrated discs, which were worth between approximately 3000 and approximately 4500, and with roughly ten of Steel serrated discs I bought out almost the entire caravan. Now of course without the mod I would have had to build more furnaces, and without the proficient weapon smiths I would have had to have built many more steel discs, but it seems to me that it's still more efficient than using stone crafts. Once you have a steel industry set up it only takes between a week or a month to make enough Serrated discs to buy out entire caravans, because the value of the goods generated would vary due to the quality multiplier which is itself dependent on the skill of the weapon smith, so it would take a skilled worker simply less time to produce equivalent value. Now I know most people have used stone crafts as a trade good, and so did I for a long time. Then I wondered why I would go through the trouble of having 2 dwarfs working on just rock crafts their entire lives, when it would take so much less time producing steel discs. One of the prominent arguments for using stone crafts is that you have to get rid of it somehow, and at least you aren’t atom smashing it when you turn it into crafts. Now of course steel is actually useful, but usually when you find a map that has both coal iron and flux, you have tons of all three, so it isn’t exactly in short supply. If you are going to haul stone to stone crafters work shop, couldn’t you just haul it perhaps even a shorter distance to a drawbridge and atom smash it out of existence? Steel serrated discs only weigh 3 pounds too, and so for pound their value is at least equivalent to if not greater than that of rock crafts.
Now for the tl;dr version, steel serrated discs are very valuable, stone is not, why do you make crafts out of stone, when you could make them out of steel for the same amount of cash per pound?
That is also the question I want to know, people must have known about this before I wrote about it so why does everyone use stone crafts?
Ps. Sorry for being so long winded
, I would suggest however that before you post you at least skim what I wrote to see if I didn’t already address what you were going to say.
