In Buck's defense, I have at least three standard production 110s with the Idaho stamp, and they are well built.
Well, make that two. The knife I sent in was one of them. Now, after the Warranty Department work, I don't consider it well built anymore. At least not up to Buck's past standards. Based on all my other 110s, I have high expectations for Buck 110s, I suppose.
Edited to add: I pulled a number of my 110s and sat them down on a hardwood floor on their back spring. Some leaned a little bit--five to ten degrees at most. Others sat up perfectly straight, particularly the older 110s. None of them leaned the way this problem 110 does. You can look down the back of the knife and tell that something is going on with the fit.
