Hello all. I live in michigan and the law here is that my folding knife has to be 3 inches or less. I currently edc a small sebenza. I'm looking to by a strider. The question I have is that a SNG has a blade legnth of 3 1/2 inches but a finger groove and a cutting edge of 2.85 or so. Does any body know if the blade length is meaured by the whole tang opened or the just the cutting edge? The answer's will make my deciesion between a PT or SNG. Thanks everybody!
