Review: Good - Good Review: SO cool! - This thing is AWESOME!! No sharp edges, and it's not super heavy, but it's not flimsy either. It seems to be pretty well-made, and it doesn't catch or anything when in use. It folds up easily as well. It's pretty accurate, comparing it to an actual butterfly knife, though the real thing is a bit heavier. But that's because a good blade will weigh more, so that makes sense, and is reasonable to consider. Excellent training tool for learning how to safely maneuver a real one. It noticeably helps improve hand/eye coordination and dexterity in general. I've seen a huge improvement in about 2 weeks in my son. Everyone in the household uses it. It's definitely a fun little guy. ## Features - NON-OFFENSIVE BLADE - This butterfly trainer is perfect for learning how to use the real thing without all the cuts and bruises to the hands.
