4 Easiest+Cheapest Ways to Make NINJA STARS at Home (Shuriken Throwing Stars) (Minimal/no tools)

About this video

ZNA Productions compares three generations of his throwing-star builds — from a first attempt in thin plate to heavier versions in saw-blade steel and riveted flat bar. The host tests each design against wooden targets, showing how material choice, weight, and blade sharpness affect performance. Throughout, ZNA emphasizes that even basic tools and inexpensive materials can produce functional throwing stars, with the humor-filled ‘secret edge-sharpening method’ serving as a comedic exploration of workshop experimentation.

Key takeaways

• Material selection dramatically impacts tool performance—higher quality steel holds an edge better and resists bending compared to thin, low-grade metal
• Design considerations like blade geometry and weight distribution should match the intended throwing method, affecting how the tool penetrates its target
• Simple hand tools like hacksaws and files can accomplish the same cuts and sharpening as power tools, though with different time investments
• Testing reveals real-world performance gaps between theory and execution—the heavier shuriken delivered more force and penetration despite the maker’s throwing inexperience
