Elliott - regarding specific use, some things I've observed with seven knives, Rough Rider (RR) and Steel Warrior (SW). I've carried all of these in rotation at one time or another, and I've included notes on specific knives.
On the advice of a police investigator, I started keeping notes/pictures on all my knives (high-end or not) after my collection was stolen back in the late 1990's. I started adding details after I joined the forums here. (This post is a cut & paste, with some editing, from my files, so the format may look a little funky.)
If you want to see images, SMKW #'s are in parenthesis.

SW Barricuda, blue scales: (FRSW100CBJ) June 2006. Okay edge out of the box, better once I took my Lansky sharpener to it. (A little tedious on these small knives.) Smooth opening, lock-up was solid, no wobble, lock was easy to use (no sticking). Once sharpened, this one held an edge for a long time, and it sharpened up pretty easily. Scales "bled" some blue pigment (sweaty palms on a hot day) but otherwise no shrinkage or cracking. This was the first import slip-joint I bought, and I used it for awhile. A good friend at ACE Hardware, who knew I liked knives, sold it to me at a discount, so I could try it out; couldn't say no to that. My only complaint is that the handle design is too skinny for me. Spring is flush open/closed.
RR 3.5" pearl-handled knife: (RR238) Dec. 2006. Good edge out of the box, fit & finish were good, pearl had some dark & some white areas, but otherwise was "lifeless" as another forum member stated elsewhere, lock was bad. SMKW credited me the price back. After seeing the pearl, I didn't really want another one. This one's relegated to letter-opener use on the desk.

RR 3-blade Jack, red scales: June 2007. (RR430) This one had the best edges, on all three blades, out of the box, and had a unique feel to it too - all three blades pivot off the small end. Pretty heavy for a small knife. No wobble in the blades. Red scales oozed a lot of pigment when I washed it, but they seem to be pretty stable otherwise. One small gap in the backsprings, but otherwise F&F are pretty good. I used every blade for everything, from cutting steak/hot dogs/fruit veggies/etc. (I use it as my pic-nic knife) and I also used it for a lot of whittling. I've used the middle blade (drop-point) for drilling holes in pine fence posts a couple of times, no problems. All three blades have solid half-stops, springs are all flush when open/closed.
RR pearl-handled canoe: (RR231) Sept. 2007. After the first pearl-handled knife from RR, I swore off them, then broke down and bought this one from Bob Tice Knives. Cost more, but it was worth the extra $ - great knife, great F&F, nice looking pearl, although one side is lighter than the other. This is my Sunday knife (a tradition in my family) and while it's only used on weekends, it gets limited use - I try not to use it where it can get dropped. Good edges out of the box, no wobble, haven't had to sharpen it yet. Springs are flush open/closed.
SW locking whittler: (FRSW116WABS) Dec. 2007. I bought this one before I realized it was basically a knock-off of the Case/T. Bose model. Blade grind was not very even, apparently having to grind such a large (thick) tang was not easy to do. solid lock-up, but flimsy looking lock lever. Edge was okay out of the box, and I cut up a lot of cardboard at Christmas with it. I had to sharpen it several times, and the point dulled from being stabbed through cardboard, but it held up okay. Pried out dozens of staples from bicycle boxes, tip held up okay. I complained to SMKW about the lock - solid lock-up, but looked flimsy - and they sent another one at no charge. A little better, blade symmetry was more consistent, lock appeared not as flimsy. I used the small blades on both to carve about 150-200 (or more?) notches of various sizes in sticks while watching tv one night. edges on the small blades were good out of the box, and I haven't sharpened them yet. Those thin blades are great for whittling & detail work. Springs NOT flush when open, but don't sit up enough to matter.

RR Elephant Toenail: (RR508) Sept. 2007. I beat the he!! out of this one, and it held up very well. Smooth opening, but a "nail-breaker", by purview of the thick backspring on the main blade. The small blade was easier to open, good edge out of the box. Edge on the main (large) blade was terrible out of the box, I think because the main blade's so thick. Good, even grinds on both both blades, but the final edge on the main blade was terrible. I spent some time fixing that, then used it for everything. I cut up a lot of cardboard & old rope with it; used the tip to counter-sink several dozen screw heads (it's wide enough for that); used it at the grill for all the cutting I needed to do for several hours at a party, including using the back of the main blade to scrape out the bean skillet; battonned it through quite a few 2x4 pieces; I broke the tip of the small blade cleaning gunk out of an old mill file I was using. Out of all of that, I only sharpened it a couple of times. My only other complaint is that there was a small gap in the backsprings, which I hate 'cause crud gets in there and is a real pain to get it all out. Springs are flush open/closed.
SW Large Trapper, bone scales: Sept. 2006. My favorite of all of these. Good edges out of the box, LARGE nail nicks, strongest springs (other than the ET) of any folder I own. I used this for 8-9 months for everything, my only complaint was that it dulled pretty quickly, but sharpened up really well.

So, a rather long post, but hopefully it's helpful. I think this is all the RR & SW knives I own, other than the RR 2nds grab bag I bought, and I haven't had time to use those enough to evaluate them.
One last note - I haven't owned any of these long enough to judge the long-term stability of the bone scales. We'll see how they look in another 3-4 years.
I gotta go run errands - I'll be back later, and post more notes if I find them.
thx - cpr
