I managed to remove all items under 2.15, simply by using the double name; I am not sure why, but it worked at least once). As for the item numbers, I think I made a mistake in my syntax, so that would explain why it doesn't work (at least for Sword of Sharpness/Bane Blade, as the Staff of Elemental Mastery is another matter altogether).

It doesn't seem to work using #selectweapon <Number> either, or by using #selectitem <Number>, even for items not sharing a same name.
