It appears that the only way to remove these items currently is to use the public Cheat Engine table, which can be acquired from GitHub which I will also link at the end of this post. Make sure you have the current build of Cheat Engine installed (version 7.4 as of 4/12/2024). To remove the items, launch Dark Souls II: Scholar of the First Sin, and load the affected character. Next, open the Cheat Engine table(DS2_SotFS_Bob_Edition.CT), and it will automatically link to your active instance of Dark Souls II: Scholar of the First Sin. In the lower section, click "Open - Table v4.7.4" > "Scripts" > "Misc" > "+14 Crash Protection". Once this is enabled, this will prevent the game from crashing due to the +14 Bleed Daggers in your inventory. From here, you should now be able to go in and remove them. To hasten the process, select one of the items, and hit "Discard Selected", and you can mass select the items to be discarded.
