Hi everyone this is my first post on Hinderer forum. I have 3.5 and 3in blade mx18s and they are awesome knives and I love them both. This is not an issue or any flaws on my folders but I was wondering what happens with the contact of the blade and the stop pin after long term of sharpening the blade? When the knife is new, you have the flat area on the choil to contact stop pin when in closed position but over long term of use and sharpening the blade would remove the flat area? end up with sharpened edge contacting the stop pin? actually I dont really use them hard so I would not have to worry about that so much but I was just wondering if any of you thought about the same thing. If Im correct the newer model with the stop pin located in higher position is better? I guess. Will Hinderer knives swap the blade if that ever happens? ofcourse I know that I will have to pay for it if thats the case.
