No. if the big goron on top of death mountain is holding his eye that's when you get the big gorons sword:-)
No, only the Giant's Knife.
As adult link, trade your broken biggorn sword to Biggoron on top of death moutain, this triggers a trade sequence.
You get it by giving biggoron the broken goron's sword.
There are only three I know of: the Kokiri sword, obtained as a child in Kokiri forest, the Master sword, obtained as a child, wielded as an adult, obtained in the Temple of Time, and the Biggoron Sword, obtained through a trading sequence, and is not necessary to completing the game.
The Zora King will give it to you went you unfreeze him with the blue fire
As Far as i know there are no "new swords" ever released, just the kokiri sword, master sword, and the variations of the biggoron sword
Not nessasarily but a little spoiler. There is a time at the end of the game when the Master Sword isnt available, but the Megaton hammer can be used too.
Just keep on bashing on that tail. This is a long fight, if you acquired the biggoron's sword it would be best to use it. It does more damage.
Too get rid of the poacher's saw then give it to the guy outside of the carpenter's tent in Gerudo valley. This is part of the Biggoron's sword trading sequence.
There are quite a few things that you get when Link i grown up. First you can get the Hookshot, which is located in the graveyard. You can also start the biggoron trading quest.
When you pull up the map screen in Hyrule Field, it will use the arrows to show you where you need to go next. The flashing arrow can refer to either the hookshot that you can get from Dampe or the Biggoron Sword sidequest. If you used a glitch after getting the Biggoron Sword to turn the claim check into a glass jar, then the arrow will always be pointing to Kakariko Village.
If by that you mean the Fire Medallion in Ocarina of Time, completing the Fire Temple will get you it.
