My point is that if you can stick with the factory setting for a while (assuming it will loosen up to something more reasonable), you will be better off in the end. It is like rebuilding an engine. Once you tear into it, it will never be the same as it was from the factory!
Once you loosen it up, you are going to be messing with it for the rest of the life of that knife. If you end up going with Threadlock, you had better get it exactly right before it dries.
