The shields on the Queen MM's are not pinned, they are glued (well, I can't vouch for the "New Queen" models).
Just took mine out of its sheath on my belt, and noticed that the D2 is darkening up nicely, with a nice, honest, earned patina. This has been my TRUE edc for at least the past 5 years, carried & used literally every single weekday (no matter what else may be in my pockets). I know there has lately been some wondering about D2's ability to take a patina, and yes it does take quite a while, but it will happen given enough time. I'll try to remember to snap some pics, when I'm back in the same space as my camera.
Also, early on in this knife's career, I used sandpaper/mousepad to convex the blade, a la Bark River. Since then, all it's needed is a periodic stropping to come right back to hair-whittling sharp.
The MM is the knife that sold me on D2, and on a convex edge, and has really proven to be a reliable companion unlike any other so far. :thumbup:
