Blacksmithing 1–450: leveling up (WotLK)

How to upgrade your blacksmithing from 1 to 450 on WotLK 3.3.5a: ore and ingots by segments, what to forge, and where to get special recipes.
Briefly
The blacksmith makes weapons, armor, shields, and at 440+ - Eternal Belt Buckle, weapon stones. One of the most expensive professions: you need a lot of ore, it is better to combine it with Mining.
Materials
- Copper Ore/Bar (Copper Ore/Ingot) - 1–90
- Tin (Tin), Bronze (Bronze = Copper+Tin) - 65–150
- Silver (Silver), Iron (Iron) - 130–200
- Gold (Gold), Mithril (Mithril) - 190–260
- Thorium (Thorium) - 250–300
- Fel Iron (Fel Iron), Adamantite (Adamantite) - 300–375
- Cobalt (Cobalt), Saronite (Saronite), Titanium (Titanium) - 375–450
Pumping by segments
1–90
- Rough/Silvered Sharpen Stone, Rough Grinding Stone - we sharpen stones from copper.

- At 400+, keep a stock of Eternal Earth/Fire/Shadow - they go into the “eternal” linings.
- Specialization (Armorsmith/Weaponsmith) choose according to what you will wear/sell.
Summary
