I must also say that this is a great model. Looking at this and reading the comments of everyone else made me go pull out my 2nd Ed. D&D Ninja Handbook to refresh my memory. Perhaps as your next project, or as a continuation of this one, you could make a Wakizashi to go with the Katana... would make a great dual-wield combination. I will quote from the Ninja Hanbook:
This is a short sword, similar in design and construction to the katana. Like the katana, the wakizashi may be named for some deed or event. It holds almost as important a place in the samurai\'s honor as his katana. Those rules and guidelines concerning the katana and its care also apply the the wakizashi when it is part of a matched set.
The wakizashi and the katana are normally worn as a pair by samurai characters. The pair is known as daisho, or \"long and short.\" In many lands, the two-weapon combination is a sign of samurai status. Anyone other than a samurai who wears the long and short swords together is subject to arrest or immediate execution.
It would be great to have a longer, sligtly more curved wakizashi to go with your beautiful katana. It would be so badass to have a ninja set like that!
Thanks for the great model, and maybe we can see a matching wakizashi sometime!?!
