I own some swords, mostly because I like them.
The pre-eminent long blade in world wide use today it the machette. This is the truth, and it's true for good reasons. First reason is that it's a tool. A katana is a great weapon, but a macette you can use to clear a trail or harvest crops. Another reason is that they are cheap and easy to get, therefor easy to replace if you use it up, break it, or drop it while you run to fight another day. That big blade made of thin steel is fearsome against bodies.
If you are familiar with asian martial arts and a little of the history surrounding them, you may be familiar with the origins of the 'classic' karate/kobudo weaponry. Weapons like the nunchuck, sai, tonfa and so on were adapted from agricultural implements. This happened because not only were swords regulated out of the reach of the common man but also because these implements could be on hand when you need them. Using the same train of thought brings us to the shovel, the can of wasp spray, the ball peen hammer, the maglight and the machette. Stuff you can get and have around. If you need a weapon, you got one. If you don't need a weapon, you can at least get some work done.
My swords are usable, but I just have them as decorations. My machette is what I would grab for anything rough.
