Fighting using Makibishi. This tiny little tool can be used in some surprisingly effective ways

The Tetsubishi, the iron diamond. No matter how this falls, it's landing point up. That's like the easiest thing to use. You're either dropping it behind you as you run away, dropping it in front of you, inviting someone to attack, or just throwing them directly at someone to keep them away. Straightforward. Throwing them is a pinch. You can throw them directly and straight. The only dangerous part is using them and collecting them and carrying them. You can throw them directly and straight.

Oh, and then retrieving them. But other than that, they're super easy to use.
