I just picked up my first congress pattern knife. It's also my first experience with Steel Warrior. It's 3.5", 440A, blue bone scales, and seems to be put together pretty well. It's got smooth joints with healthy springs, finish is good and there is no blade rubbing. I'd say it's a pretty good deal for $15.
I do think the blades are rather thin compared to other pocket knives I have. Is this simply a matter of it being a $15 Chinese knife or are congress blades typically thin in order to fit 4 blades in a small handle? I can't complain too much since a thinner blade will likely slice better. I don't rough up my knives too much so I'm not concerned about snapping a blade.
