I finally ended up purchasing a BM Pinnacle 1st Production Run a couple of days ago. The store that I purchased from had 3 in stock. I inspected all available before deciding on the one I purchased. The first one had a problem with the lock, the frame did not engage the blade enough to lock it. I was able to tap the blade closed with a finger after opening same. The second one I looked at had a similar problem, the frame lock engaged only slightly and did not instill any confidence that it would remain open under working conditions. The one I purchased had a strong lock-up and the frame engaged about 3/4 of the way.
I do like BM knives and own several, I have not had similar experience with other models.I don't know if the fact that it was 1st production run had anything to do with it and I know they have had problems with consistency. Just wanted to let you all know about my experience.
