This is a great self defense tool. Out of the box, the daggers are sharp. They are incredibly intimidating and really good for self defense purposes. I personally would not want to be punched by one of these. I punched a hole into a sheet of MDF. The only downside is the daggers are made of 420 stainless steel. 420 relatively easy to sharpen though. The sheath could be ABS plastic. Either way, it is still a decent sheath. These daggers are well worth their money and I recommend them for serious self defense.
