This page contains the list of weapons needed to unlock Knight's Honor achievement/trophy. All of these need to be collected on one character to unlock the achievement/trophy. The Steam version, however, seems to track weapons across characters.
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 all as there are 3 different weapons needed to craft with the Soul of Sif. However, it is possible to obtain a boss soul by having another player give drop it for the host.
Having Additional Content does not have any effect on this list as only base game weapons are needed to unlock Knight's Honor.
These weapons are required to be crafted from the corresponding Boss Soul and the required +10 Normal weapon (except for catalysts, which cannot be upgraded). Soul weapons are crafted only by the Giant Blacksmith in Anor Londo.

Dropped by Darkwraith Enemy.
Dropped by killing various enemies. Most weapon drops are rare, so boosting Item Discovery rate is a must.

Maximum Item Discovery value is 410.
