As for the "problem" of DMs losing track of what various items do, we-ell, I have no sympathy whatsoever as it's incumbent on you as DM to keep track of items anyway...an item numbering system can be a big help here - every time you give out an item (magic or not) in treasury, give it a number. *Insist* your players record the number on their sheets along with the item. Keep your own list of items in numerical order. Then, when someone swings with an unidentified sword you just ask "what number is it?" and can then easily reference your list to remind yourself what it does. This becomes essential when a) items have properties unknown to the characters/players e.g. curses, and-or b) when there are several similar-on-the-surface items e.g. "+2 swords" in a party but they are in fact not the same at all...item #36 that Sharana is using is in fact +1 to hit/+3 damage, item #38 that Astacoe is using is a straight +2, while item #39 in Khurin's hands is +1 base with extra benefits vs. dragons only. But they all radiate about the same level of magic and the party have assumed they're all +2's...it's up to you to keep them straight until such time as the party gets them ID'ed - if ever.
