While I've never bought a knife strictly because of a review, when I am interested in a knife I watch/read every review I can find before purchasing. I would say earlier in my knifedom reviews, particularly nutnfancy, were very influential. Now that I am more knowledgeable and know what to expect from most companies the videos are less influential. Now they are more to expose any little negative surprises. For example I used to want a D.O.C, but after hearing about issues with the clip and unusually strong detente, I decided otherwise.
