This is an extremely condensed guide to getting your Blacksmithing (raw, not weaponsmith or armorsmith) to 300.

AZEROTH

1 – 25
Rough Sharpening Stones (1 x Rough Stone) x 50

25 – 45
Rough Grinding Stones (2 x Rough Stone) x 20

45 – 75
Copper Chain Belt (6 x Copper Bar) x 30

75 – 80
Coarse Grinding Stones (2 x Coarse Stones) x 10

80 – 100
Runed Copper Belt (10 x Copper Bar) x 20

100 – 105
Silver Rod (1 x Silver Bar, 2 x Rough Grinding Stone) x 5

105 – 125
Rough Bronze Leggings (6 x Bronze Bar) x 20

125 – 150
Heavy Grinding Stone (3 x Heavy Stone) x 50

150 – 155
Golden Rod (1 x Gold Bar, 2 x Coarse Grinding Stone) x 5

155 – 165
Green Iron Leggings (8 x Iron Bar, 1 x Heavy Grinding Stone, 1 x Green Dye) x 10

165 – 185
Green Iron Bracers (6 x Iron Bar, 1 x Green Dye) x 20

185 – 200
Golden Scale Bracers (5 x Steel Bar, 2 x Heavy Grinding Stone) x 15

200 – 210
Solid Grinding Stone (4 x Solid Stone) x 20

210 – 215
Golden Scale Bracers (5 x Steel Bar, 2 x Heavy Grinding Stone) x 5

215 – 235
Steel Plate Helm (14 x Steel Bar, 1 x Solid Grinding Stone) x 20

Alternatively, you could go and buy the plans for Mithril Scale Bracers from either Gharash in Stonard, Swamp of Sorrows or from Harggan in Aeries Peak, The Hinterlands. It’s a limited supply recipe, so you may have to try a few times. It works out cheaper to make these than Steel Plate Helms.

235 – 250
Mithril Coif (10 x Mithril Bar, 6 x Mageweave Cloth) x 15
If your lucky enough to get the Mithril Spurs plans, then make those till they turn grey at 275. It’s by far the cheapest way to level. Unfortunately the plans are now selling for anywhere up to 300g since TBC was released.

250 – 260
Dense Sharpening Stones (1 x Dense Stone) x 20

Whilst your grinding for the mats for the 260-265 part, keep an eye on the AH for either the Thorium Belt or Bracers plans. As these are much, much easier and cheaper to make

260 – 265
Armoursmiths make the following:
Earthforged Leggings (16 x Mithril Bar, 2 x Core of Earth) x 5

Weaponsmiths make any of the following:
Light Earthforged Blade (12 x Mithril Bar, 4 x Core of Earth) x 5
Light Emberforged Hammer (12 x Mithril Bar, 4 x Heart of Fire) x 5
Light Skyforged Axe (12 x Mithril Bar, 4 x Breath of Wind) x 5

Go see Derotain Mudsipper in Gadgetzan and give him Thorium Bars untill you get the plans for the Imperial Plate Belt, Bracers and Boots.
Should be about 50 Thorium Bars, but if you want the whole set, it’s 130 bars.

265 – 275
Imperial Plate Belt (10 x Thorium Bar, 6 x Rugged Leather) x 10

275 – 295
Imperial Plate Bracers (12 x Thorium Bar) x 20

295 – 300
Imperial Plate Boots (18 x Thorium Bar) x 5
