HK1 Hydrokinetic Adjustable Wrench

After stumbling upon the video for this product on Youtube, I bought this wrench out of curiosity a little while a ago, and was pleasantly surprised. It works great. It has a valve in the center that allows you to adjust the piston to the size needed. I did find the pistons a little stiff in the beginning but they loosened up after playing around with it for a bit. Overall i am really pleased with it.
HK1 Hydrokinetic Adjustable WrenchI just received this tool this week and I gotta say it is really cool. The quality of the tool is great and very precise. I have every type of slide adjusting Crescent like wrenches that either have sticky slides or don’t hold the setting on the nut. This holds fast. Great tool for your utility belt, seriously.
This is the coolest tool to come along in years.
I’ve already used it a few times and it works really well.
I’m impressed!
Not for everyday use, but a hero tool for the mobile tool box in car or for emergencies. I am very impressed with heft and apparent quality of the tool and mechanism
