Most of the time in Guild wars 2 you will have to buy your gathering tools and salvage kits with gold. Around the world of Tyria you will fin renowned heart karma vendors that do sell tools and kits for karma but usually only one type.
In Lion’s Arch there is a npc that sells all tiers of salvage kits and gathering tools for karma points. her name is Frayja and she is a Master Weaponsmith. She is located in the crafting area of Lion’s Arch with the shield weaponsmith icon. Check ot the pictures for more details.
So if you don’t want to spend your ahrd earne gold on tools and salvage kits you can buy them with karma.The professions chart will not represent the live distribution, as this was taken from a beta weekend, and there will be far less jewelers and more cooks. The interesting thing to note from this section is the armor making crafting disciplines, that are essentially equally represented (there are less armorsmiths because there are only 2 professions who use heavy armor).
When a GW2 player makes their first character they will have a 20 slot starter backpack and four bag slots. They will also have 30 shared bank slots and a special bank for crafting materials which has a capacity of storing stacks of up to 250 items of one crafting material.
