I was trying to order the 500 Eagle Scout knife. I requested through customer service that the lock bar be flush while opened and closed and that the blade be centered when closed. The lady from customer service called me (she was super nice, by the way) and said they tried to find me a knife that met my requests, but couldn’t. The tech told her that it is impossible to have the lockbar flush open and closed while simultaneously having a centered blade on the 500 due to the build/structure of the 500. I’ve had many lockbacks that met these criteria, so I didn’t really understand the tech’s explanation. Often too much is made over blade centering, but I have also bought knives from the 500 series sight-unseen where the blade was rubbing the liner, so I just wanted to request a centered blade in advance. Can anyone explain this to me? I’m not complaining; I just want to understand this better. Thanks in advance for your thoughts.
