Cerbera, no I don't. Not yet. I know what I have with my multi-tools, but I will admit, SAKs tend to look a lot alike. Now that I have them semi-organized, it should be easier to ID them and make a master list. As for the Display knife, I have no history on it other than it is very well made, heavy, and big. The tools have no back spring tension, even though there are metal pieces that look like back springs. The tools are just rounded and thus don't lock. The bottle opener doesn't close due to a slight thickness to accommodate a small threaded hole. My guess, it is meant to attach to something there, or it is meant to be like it is in my drawer, splayed out on a flat surface to catch the eye in a display case.
Sea Monster, what is the point of spending on more items when you can't display and secure them properly?
