Different Descriptions of Common Items for Variety

One of the issues I ran into pretty frequently as a beginning DM was that I was thinking of most of the parts of the world as interchangeable. By this, I meant that a longsword was simply a longsword to me--any longsword was essentially the same. This is in part because the game rules dictate that essentially all longswords are the same according to combat rules. But of course, no two longswords are going to be exactly the same. So this is a guide to common items with a variety of descriptions to keep your game fresh.
