I received my new 175 in the mail about a week ago and I have to say that I am disappointed. It had been replaced (which I really appreciate), but the knife is not what I expected from buck. The blade grind is very poor. It is uneven on one side and the edge is ground deeper than the low points in the serrations. With this muck metal removed, I became concerned that the temper of the blade may have been "burned." To make things worse, it was not even very sharp.
Also, the blade rubs on the inside of the handle. This is not consistent though, depending on how the blade has been used or if the knife has banged on something, the blade may or may not rub. I think that if the diameter of the spacers between the blade, liner, and scale is increased (like on a CRKT Mirage), it might help straighten up the blade when it is closed and prevent it from rubbing on the scale, as a result of the pressure from the lock. I guess I'm just picky.
Have any improvements, such as I have described, been made to the Y2K models? If so, I will just have to buy another one when they become available. I guess for now I will have to carry my carbon fiber 182, which, by the way, has exceeded my expectations. The action is very smooth and the lockup is very solid. The CF looks great!
