Unlimited in use ? That sure does change things. I would mostly use them to off set my opponent, cause them to dodge rather than counter by using a rain of kunai along with the elemental attacks from my masks (Kakuzu).Mkay, allow me to go over your points. ^_^
-Ninjutsu is actually a very general term and also includes the Basic Five in it. I can't teach you Kakuzu's techniques, haha, but there are indeed a lot of creative things you can do with the Ninjutsu we are learning, which is more focused upon the use of chakra and ninja weapons.
-Haha, Genjutsu and Taijutsu would be sad without you.
Alright, let's start a bit simple. I'll like to emphasize over how vital ninja tools are as there are no restrictions regarding them so you can use them as much as you can and as creatively as possible.
Let's take a look at the kunai.

How do they work and how do you personally plan to use them in battle?
Alright, i'll be sure to use a sufficient amount.Unlimited, but keep it rational.
Okay, very good with keeping it in conjunction with Kakuzu's abilities, but let's take an actual deeper look at the weapon itself.
There is a hole on top of it, designed purposely for the use of attaching what kinds of things?
Also, say that you were locked in close combat with your opponent and you had a kunai in hand. Where would you strike to deal instant, fatal death?
I honestly only remember Itachi's use of it, he somehow infused fire into them and used them in quick succession to make it seem like a Ninjutsu based attack in itself.Excellent. So do you remember what Sasuke did with his shurikens? How did he affect them with his element?
