I'll second the Tuff if you want to try one. Only issue is the lock can be a little slick on some models, so stabbing is a bad idea. Great way to try out 3V steel though, which is superd for impact and has insane levels of toughness.
I don't really have any "sharpened pry-bars" right now, but I've had my fair share of them over time
I tend to stick to slimmer folders overall now, with more of a slicing and overall performance focus, but the Adamas is a very nice knife. I wouldn't personally consider it impractical either, as it is strong, and has a very good overall construction. A little too thick for me, but still a very nice knife
Never got into a DPX, but though about it. Might pick one up if I find a deal on one

I liked my Strider SNG a lot more than I though I would, and it was very tough. Still regret selling that one, and I will be getting another one, just not sure when...
I will say that the Redencion 228 midtech would be very good if it wasn't on bearings. The bearings they use are teensy tiny, and really won't give you much strength around the pivot. Oh what i wouldn't give for a 228 on Phospher bronze washers with maybe a bushing pivot system... oh well
I like tough folders, and I like the feel of some overbuilt folders, but I like things that are practical too. Not a hater, just more of my taste. The Ferrum Forge Ferox is a good example. Yeah its on bearings, but the lock is very strong for a Ti framelock, and the bearings have a wider radius to give it more durability. Plus the 4V still comes to a good thinness behind the edge and performs very well.
