No, you can't rewrite an item's stats via the console, you'd need to mod it with the construction kit.
I don't really know so please help me.
It's almost impossible but you can
you cant you have to steal them
There are pre set weapons that you can inchant but you can't make a weapon from scratch
Chrysamere doesn't appear in vanilla oblivion, and I'm not sure of any mods that add it.
No you cannot. It is just an object.
the bound sword is a bound daedric claymore. that weapon is tied with the daedric warhammer.
There are two ways to get your weapon enchanted or "special." The sigil stones you get from closing oblivion gates have two enchantments on them: an offesive one for your weapon or a defensive one for your armor. If you are the Arch-Mage, then you can use the Altar of Enchanting to enchant your weapon, provided you have a filled soul gem available.
Your fists. And the flare spell. But as in like a real weapon, either a steel shortsword or Renavaults Akaviri Katana
It is fairly easy to mod oblivion for the PC. You can't get a pistole in oblivion for the 360 or ps3 but some one could make a new weapon type and design a pistole or for that matter anything. Oblivion is a canvase to what ever you want in a game
use a weapon made of silver or druidic
if you have oblivion on the PC you can type in the cheats menu coc testinghall here you will find rooms with every weapon, armours and other cool stuff.
