I've had two different tip-up knives partially open in my pants (I IWB carry) and while one just scared me a little, the other--an Endura--impaled my hand beneath the thumb and the tip ended up under the skin of my palm about 1.75" in. Thanks to the extremely fine tip and the edges I keep on knives, it didn't even hurt at first and nor did I realize what had happened until I brought my hand back to the front; just an odd burning sensation. A WHOLE lot of blood, swelling, five hours in an ER and some stitches later, the hurt happened.

I personally no longer have any use for folding knives with their tips up where gravity is working WITH the pivot. I'd rather have it working against it. For those who pocket-carry their folders it's less of an issue as the pocket corner hugs the tip closed, so I understand the appeal somewhat, although I still wouldn't desire it, because even back before the accidental openings I always found tip up very awkward as compared to tip down. Fortunately, all of my favorite Spydies are either tip-down only or can be configured that way.
Anyway, as to the Military itself, I'm finally getting my first, and have to admit to being somewhat...curious about how I'll like it. Not knocking anybody else's preferences, but I tend to gravitate towards heavier folding knives, like the original Manix, Lionsteel SR-1, XM-18s and others like that. The Military is always described as being so light and "like it's not even there" that I've long considered it not even worth looking at. Nonetheless, it has what seems to be an almost religious following, and many of the devout are fellow knife knuts whose opinions I've long respected, so I finally took the plunge this morning and ordered Newgraham's last fluted titanium Military, as it seemed to me that the heavier material might make it feel slightly less "wrong" for me, and the flutes might give slightly better traction than plain ti scales. I'm also more a fan of frame locks than liner locks, so that's a plus as well.
I don't imagine for a second that I'll DISlike it, and will be careful not to make snap judgments just due to it being different than my normal preference. I'm just interested to see how I feel about it after a couple of weeks. In some cases, knives that I've taken convincing on have completely blown me away when they showed up, and in others--like the Sebenza--I was able to appreciate why others appreciate them but didn't fall in love myself. If I don't like it, I can probably find somebody who would. If I love it, then I face the problem of finding a spot for it in the folder drawer, assuming I ever want to carry anything else again!
