I just got a new s&w m&p tactical knife that I ordered from kennesaw online. The knife opened like it should 3 times now it is locked closed. I will be sending this knife back. My question is that the blade and safty does not look like the one on s&w's site did they sell me a knock off? It does have the s&w symbol and the correct m&p markings but every other place I have seen the blade and safty are different.
