Hmm... interesting.

We our quick search revealed the common lengths only. But your statement there about practical use [@NuttsnBolts], is one we had in mind too. Over a certain length, a bladed weapon isn't of much practical use. Sure, you can use it, but it ain't practical.

Its one thing to make a long weapon. Its quite another to make a useful long weapon.

From seeing that, they did say it has one practical use if you forget something. :P
