When playing single player, it's impossible to obtain every weapon in one playthrough, due to the boss Souls required in order to craft some of the rare weapons. It takes at least until New Game++ in order to get this, as there are 3 different weapons you need to craft with the Soul of Sif. However, it is possible to obtain a Boss soul by having another player give them to you.
Having Additional Content does not have any effect on this list. You only need the base game to unlock Knight's Honor.
These weapons require you to craft with the corresponding Boss soul and the required +10 Normal weapon (except for catalysts, which do not need upgrades). Soul weapons are crafted only at the Giant Blacksmith in Anor Londo.
Rare weapons that are obtained by cutting off the tail of certain enemies.

Dropped by Darkwraith Enemy.
Dropped by killing various enemies. Most weapon drops are rare, so boosting Item Discovery rate is a must. Item drops are boosted by equipping either the Covetous Gold Serpent Ring or the Symbol of Avarice (these two items don't stack) and increasing Humanity (Item Discovery bonus from Humanity maxes out at 10 Humanity). Maximum Item Discovery value is 410.
