Dear Mr. Glesser and Spyderco. Thank you for spoiling us with great and improved models. The Military is a knife I love big time and I wouldn't change much in it.
However, I think it would benefit from a compression lock (minimal and nested). Lightweight is one of the things I love at this knife and I'd like it to stay this way.
I don't know what the "Stop-lock" looks like, but if it doesn't allow an open construction, I'd leave it alone.
I'd also forsake the plastic spacer. The first thing I did when I got my Millie was to remove it and leave only those cylindrical ones, which are, IMHO more than enough and make cleaning even easier.
The CF handles are the best, IMHO (at least I preffer my CF Millie over the regular G-10 one), but I realize that G-10 has a word to say too, so I'd say any of them, just keep the steel liners (if you can't do without them) as small as possible.
Speaking of handles, I would make them a bit smaller. The way they are, they seem to have a lot of unused space (if I may say so). I would bring the spacers closer to the edge of the blade (knife closed) and cut down the surpluss. Not too much, I don't want a Police after all
