"There is a very distinct difference between what's legal and what's moral. The involvement of Paradise in our affairs will create concerns with legality, and we will often have to do things that are technically illegal in order to do what is unquestionably moral. For example, I couldn't just hand over a deadly weapon to you in one of the common rooms could I?"
Tom stepped closer and examined the sword in Keiichi's hands.
"The art of crafting a sword is far more then just putting a blade on the end of a handle. Most swords are built for balance, there's equal weight between the blade and the hilt, you can balance it on one finger. The balance is there because it's designed so that your wrist is the pivot point. You don't need to swing from the shoulder. Your elbow or wrist will give you as much cutting power, with more speed.
It's also very sharp, so be careful, though I anticipate that you will cut yourself, so it would be good to invest in some bandages."
