I got around to making an actual instructable.
That's a big thing, I usually just post pictures of finished projects. Part of the reason I'm making an instructable is because this sword was actually done when I started (thus the name "Frankenstein"). Then it broke, and I decided that when piecing it back together (remaking it), I would take pictures and turn it into an instructable. The original version of this sword is pictured here: http://www.instructables.com/id/Ninjato-20/ As you've probably taken from the "2.0" bit,
I have another ninjato that is "1.0", and a 3.0 dagger. I'm working on getting pictures of a new 2.1 into a suggestable (suggestions, not instructions, aka pictures). Every weapon is unique, however, so it's a bit hard to categorize them. Here's a more in depth explanation of the different "models" of swords:
2.0 swords (this one included) are harder than the 1.0 and 3.0. However, they are much thinner than the 1.0, and the blades look significantly better. In some cases. The long sword 1.0 is pretty regal, but maybe that's just nostalgia. It was Laertes's sword in our production of Hamlet. It all depends how you make it. On the matter of plays, the 2.0s make better stage props: harder, slightly, but more realistic. The 1.0s are better for smacking people. 3.0s, can be carved to look all fancy, and though they're pretty firm, they're lightweight and made of foam, so they're best for LARP. Suggestions are more than welcome.
If you don't understand something, or I missed something, by all means, say so and I'll try my best to help. Comments and pictures of what you've made from this instructable, with explanations of what you improved upon are certainly helpful. Ratings are useful feedback no matter what number of stars you choose. My main goal is to help other people make this - and maybe even help me improve my own swords. In any case,
here's my first try at making a full instructable.
UPDATE: This sword is actually kind of out of date now, so you might want to check out my latest weapon-making methods here
