I am also in the "dissapointed" camp with the Knipex pliers wrench.
I think it has a few very unique features and uses, but its not a replacement for an adjustable wrench or some good pliers.
I have used it primarily for tweaking and straightening sheet metal, as the parallel jaws with no teeth are perfect for adjusting things you can't scratch.
I have yet to use a "dry cut" chop saw that isn't a hot pile of garbage. They're all the rage for the hobby homeowner, but can't hold a candle to a real cold saw or bandsaw. I requisitioned one at a shop I used to work at to try it out based on reviews I had read on TGJ. We only had one cold saw, and it would have been handy to have a spare saw for the times we needed 2 guys cutting something at once. That thing was straight up dangerous, as it would very easily jam, **** the part out of the vise, and break off the teeth. Within a few days, the other employees had managed to destroy 2 blades and bent the vise screw from attempting to keep it tight. It was LOUD, shot hot chips all over the shop, and the blades cost more than the real cold saw. We bought a good one, too, MK Morse. We went back to using the Bewo cold saw that was 50 years old and hucked the dry saw in the dumpster.
Plasma cutters are handy, but not the godsend some make them out to be. There's only a few situations where I use my plasma, and its very rare. There's almost always a better way to cut metal. I find a cutoff wheel is a much cleaner cut with no smoke or dross on thinner stuff, oxy-acetylene is way nicer on thicker steel, sheet metal is cut on the laser or shear whenever possible, and a vertical bandsaw handles most everything else. I really only use the plasma on stainless curves that I can't fit in the vertical bandsaw or onsite somewhere.
