Query: Good, but not as good as the real thing.

This is a great purchase if you are not sure you want to get a feel for the butterfly knife. It weighs about four and a half ounces. Heavy for a knife but great for training. It only lasts for about 2 weeks of flipping. With mine part of the handle snapped after 2 weeks. the break was just above the latch but it still hung on by one side. If this happens to you Do Not remove the broken peice. Doing so will throw the balance of the knife making it much harder to flip. Other than a short lifespan, the knife needs oiled once in a while. Those are the negitives. The positives are: works well, great for training or experimenting, and you will not get cut.
