I'm not really up on Strider and I took this one in on trade to try it out. I would like to know if anyone can ID its generation and possibly let me know why it would only have one thumbstud? It seems a little easier to open missing it on the right side but I want to make sure its legit before moving forward in the trade. The explanation on the thumbstud was that it was replaced that way from Strider at request. I was a little surprised they would do that at request. I probably being paranoid but better safe the sorry with all the counterfeits out there. All the other details of the knife seem in order, weight, steel, logo sharpness
