The first that come to mind are several POS knockoffs I bought when my paranoia first asserted itself, but before I found some serious knives. Actually, one of those is a fairly decent knife, but no clip, so has to be carried in a sheath. Probably more like the Chinook than any other real knife I can think of.
I guess I'd have to list my Gigand Shockwave (??). I bought it because it had a cryoed AUS8 wharncliffe blade, and G-10 handles. Well, the thing came without the weird wrench they're supposed to have, that fits into 2 little indentations across from each other on an almost 1/2" pivot. The pivot will not stay tight, without rendering the blade too tight to move. I know the answer is locktite, at a reasonable tightness of the pivot. But, just as I never got around to getting the wrench, I don't do that either. One of the 3 clip screws has left of its own accord, and another is loose. They only batten down to the G-10, not the liner. It has great, thick liners, but with a split that leaves the thinnest liner lock I've seen, and wouldn't trust at all in a torqueing situation. The blade is great, the rest of the knife sucks. So it just sits in a basket.
