I had to weigh in heavily in favor of the Military. I have both a PE and a SE. I find I prefer the PE 99% of the time. I'm a pain in the neck when it comes to my equipment, rarely happy or satisfied. Even when I have something that works, it doesn't take much to get my eye wandering to replacements that
might, maybe, somehow be better. This has
not occurred with the Military.
Sharpening has been no problem, I use a Sharpmaker 203. I've sharpened it many times, because I like it to cut like (read with a Dr. Evil voice) a "laser". It does, and I'm no sharpening wiz.
I mostly carry it inside the waistband, on duty and off. That's about 14 hours a day, sweating on it in the summer, getting rained and snowed on, you name it, for I don't even know how long, the past two or three years. It's hard to remember a time without it. I just got home from work and it's clipped to my sweatpants right now. Features like nested liners and an over sized opening hole to name but two, make the Military a really high-speed piece. There's a lot longer list than that, they're just two of my favorites.
The lock has been absolutely reliable. Yes I've done things with it that I shouldn't have, that placed undue stress on the lock (don't tell Sal

) -Never had even a hint of trouble.
I'd love to tell you what I don't like about this knife, but there isn't a single thing.
Not one. I use it for food prep. I open my mail with it. I carry it at work, as I said. It has saved a life. It's cut dynamite, C4, Detcord, Detasheet and ANFO. It's cut miles of string, acres of cardboard and enough newsprint to run The Times for a month. It is a masterpiece of design. When Sal came up with this one, he really hit it out of the park.
