Question Materials Usable to Create a sword

I'm trying to assemble as complete as possible a list of materials which could be used to make a blade from. It doesn't have to just be for a sword. A blade for an axe or a knife would also be included.

So far I have the following list: Anything that could conceivably used in a medieval fantasy setting I would like to add to this list. Any assistance is required. Notice I'm including wood, glass, etc. -- things that would be highly ineffective and/or impractical but could still have a conceivable purpose.

...

Here's our list of object materials:

"cotton",
"leather",
"glass",
"gold",
"organic",
"paper",
"steel",
"wood",
"bone",
"crystal",
"ether",
"adamantine",
"mithril",
"iron",
"copper",
"ceramic",
"satin",
"silk",
"dragonhide",
"burlap",
"velvet",
"platinum",
"obsidian",
"wool",
"onyx",
"ivory",
"brass",
"marble",
"bronze",
"pewter",
"ruby",
"sapphire",
"emerald",
"gemstone",
"granite",
"stone",
"energy",
"hemp",
"diamond",
"earth",
"silver",
"alchemical silver",
"cold iron",
"darkwood",

Here's a neat list of exotic materials too (from d20pfsrd.com):

Adamantine
Angelskin
Blood Crystal
Bone
Bronze
Bulette Armor
Cold Iron
Darkleaf Cloth
Darkwood
Dragonhide
Dragonskin
Eel Hide

Frost-forged steel
Gold
Greenwood
Griffon mane
Living steel
Mithral
Obsidian
SerpentStone
Silver, Alchemical
Silversheen

Viridium
Voidglass
Whipwood
Wyroot

Most of those are either a bit too specialized for my purposes, or they fit into existing materials.

However....


Mithril, Bronze, Obsidian added to the list. Thanks!

Actually a few more of those could also be used.
