This is the World's first hydrokinetic adjustable wrench and is the only box-end wrench you need. It is as slim, reachable and strong as regular wrenches but you only need to carry one. It got very high evaluation by 'Popular Science' and 'Tool Snob'.

See other reviews - this wrench is too hard to adjust. Takes at least two, maybe three hands to hold everything, adjust, and lock. If it were redesigned to allow a thumb adjust and a finger lock, it would be a winner.
Also, remember that this is a box-end style wrench. Not every bolt or nut can be loosened with it. You'll still need a good old crescent style wrench in the toolbag. So then, you may well ask why you need it...

This wrench is a new angle of an ajustible wrench that has been around for years. The HK1 is designed to fit a nut or bolt by sliding a center piece of the wrench within the formed 3 sided body of the fixed wrench side to add a fourth side that pushes tight against the open side of the wrench. In other words, this wrench will tightly grip a normal six sided bolt or nut by at least 4 sides making a tight fit to tighten or loosen a bolt or nut. I ordered one of these because it looked neat and appeared to be a modern solution to tightening or loosening a bolt/nut. This wrench is not as convienient or as fuctional as a normal adjustible wrench. And, because the sliding action within the wrench that makes up the fourth side is quite stiff, I rate this wrench with 2 stars because it is not as functional as the regular Craftsman or Crescent adjustable wrench. If the sliding part of the wrench worked more smoothly and lightly, I would rate it 1 star higher. Sometimes I get suckered into believing a new design would be superior to the old. This is one of those times. It is just a neat looking idea that does not serve its purpose as well as the simple and cheaper adjustable wrenches on the market. Even though it does not work well in practice, it is still a neat looking tool.

This wrench seems to work OK but is a little hare to adjust. There is an opening at each end, one for larger nuts and one for smaller. You have to stick your finger into the one you are not using and slide the center bar into place by pushing it. It would be difficult for someone with big hands. I wouldn't buy another one

A little tricky to adjust, the locking knob is small and is somewhat difficult to manipulate. Also, you may have trouble moving the post if you have very large fingers. But an interesting tool anyway.
