For those of you who have played the original .hack games(infection through quarantine), how big of a logic jump is it from the semi-circular Hell Blades, to a pair of bladed Tessen? any opinions would help.

BTW, this is for a hobby project to create a personal version of "The World" from the .hack games(original and G.U.). I do not expect much success in this, and this is just for the heck of it. So no flames about my project choice.
