From my testing, what you are seeing is just the metal edges wearing in from a freshly machined edge. I have removed and installed mine many times over and have not noticed any significant deformation. It is RC40 hardness on the steel tang and will most definitely hold up much better than the titanium equivalent. Please let me know if you have issues in the future.
yes it’s a pain the ass to remove, that is how I designed it how often are you removing the bolt? You can be confident that it will remain in place under any circumstance.
