For the price I really like this trainer. I will say that the edges of the blade could use some slight rounding because you will feel it on the ricochet & can be quite painful after a while. Also it didn't come oiled so moving it was quite stiff. After all that it works really good & love the spring latch for the price. Very squeaky though. Chirps like bird while flipping it. That's no biggy, though.
Bought this to work on more advanced skills and aerials. Dropped many times, on carpet, on hardwood, and on concrete. It's tough, still haven't broke it after 3 days of constant use. Slides smooth. The handle is a bit slick so it's easy to lose grip on, other than that it's great.
I really love this practice knife, I've been planning on buying a real one soon so the is perfect for me.
