Not ninja Aside from being very flimsy, it isn't even a ninja sword. Ninja swords aren't curved they're perfectly straight. Katanas (which would have been just as "cool" to name the thing) are the ones that have a curve. It makes a decent "generic Asian" sword for a kid's costume, but otherwise it's a waste.
Flimsy and breaks easy I bought this sword because I needed a good, plastic sword to spar with. It arrived on time, but the blade is very flimsy, and in fights it often shook back and forth. It was fun to fight with until it broke (Which was in 3 weeks.) If you want a sword to spar with, keep looking. You might even want to take a look at a boken (wooden sparring sword,) those look really good with costumes, and hardly ever break (only after intense boken-on-boken battles do they crack.)
Extremely flimsy Bought this for my nephew, who loves Afro Samurai. It was the only one I could find with a sheath and for the price, I figured I'd give it a shot. It didn't last long, maybe 2 weeks. Not worth it, even for the price.
plastic if you want a plastic toy sword you cant go wrong a little flimsy, but not bad
