(1) Buck Strider Spear Point
Haven't handled one, but seems like I'd agree with those who've posted about it already. Supposedly pretty well made, for what it is. Certainly inelegant, design-wise. If you need something that overbuilt, get a small fixed blade custom made in 3V and get a good custom sheath built to make it easy to carry.
Quick bullets from here:
(2) Spyderco Military
* I own one.
* Get S30V... best balanced stainless going, and toughest stainless period.
* Spyderco quality
* Relatively thin handle, relatively long handle. Interesting design... can choke up, or put hand nearer to butt (not sure why you'd do this, since I wouldn't chop with a folder). Pretty good ergos overall.
* blade-to-handle ratio is inefficient relative to most knives
* flat ground blade is nice, but coupled with pure distal taper, you get a very sharp "pointy" point, but one that is a bit fragile given the knife's personality. S30V might help a little.
* Could ramble for long time on liner lock on this one, but suffice to say I like it fine overall. The radiused tang is a great idea, well executed, should make it wear well over time. If concerned about accidental release, the "serrations" that protrude below handle can be ground off.
* Poster indicated huge knives are not a problem for him, but this one is at the outer limit for what I'm willing to carry in front/right pocket. I'm 5'-11". Too complaints... it kinda pokes my leg when I sit, and the huge Spyder hump makes it hard to stick hand into pocket to grab something else (frequent e.g., coins).
(3) Al Mar SERE
(from memory, I sold mine)
* good ergos, beefy handle, beefy liners
* mine inexplicably failed the spine whack (moderate whack on a mouse pad). I couldn't believe it. They may have figured out what was wrong in production, I dunno. Find a knife shop, handle all they have, take a mouse pad with you, whack them all and find one with a good lockup. I'm kidding. I don't know how to get around this.
* useful blade shape, most useful of what you list for game cleaning, given it has a spear point (Carson Model 4 DP or CP and Spydie Wegner are significantly better here)
* Lots of people like VG-10, I don't own a knife with VG-10. I'm surprised how well it's liked given the alloy composition. If Jeff Clark says it gets sharp, it gets sharp.
* blade profile a bit thick as Roadrunner stated, can compromise by doing say 20deg per side.
(4) Spyderco Chinook
(handled, never owned)
* Big knife. Beefy. Spine lock is really stout, arguably safer than liner lock.
* Fairly long handle, drop at butt means secure for draw stroke.
* Spyderco quality.
* I'm not a 440V fan at all... too soft, rolls easy, but fine grain yields a super sharp edge, and it is abrasion resistant stuff. Others like it fine it seems.
* I don't like upswept blades... would take almost any profile before upswept, search on James Keating and you might find out exactly why he wanted upswept... he likes sharpened secondary edges for backcuts. Knife fighting stuff. Not my cup o tea. YMMV.
(5) Microtech Manual SOCOM
(Owned one, sold it)
* Microtech quality is best in production world
* people love or hate the microbar, I liked it fine, seemed unlikely to unlock accidentally the way I use knives, other may think there's too much index finger engagement in use. One fact of Microbar is that is does rely on a small spring (coil?) for tension, which can break. Can find older ones with liner lock I believe, with patience.
* heat treat of 154CM seemed to be quite good. Sharpened up nicely (whereas some latter day BM's in 154CM were a bear to sharpen and didn't take much of an edge, not easily). Heat treat matters.
* I don't mind metal handle, don't love 'em either. But they are a bit slick even with inserts. Not good for, say, Alaska carry (cold). I prefer grippier and "less cold", e.g. G-10, Micarta, or even wood.
* Loved blade profile, looks very cool (the "clip", not the tanto)
* Only thing I didn't like... handle is triangular shaped, in that it narrows towards the butt. Makes it feel insecure in draw stroke, although this is 1/2 in my mind and 1/2 real.
* blade profile a bit thick as Roadrunner stated, can compromise by doing say 20deg per side.
Your answers to the questions didn't really rule out anything.
