The Job Knob - MADE IN USA!
Acetylene tanks are exchanged over the counter at supply houses across the country on a daily basis. Many of these tanks do not come with a mechanism on the valve to open them, only a metal shank. Currently technicians use any tool handy to open the tank, from channel locks and pliers to wrenches.
The Job Knob offers the user the ability to open and close the valve with ease without jeopardizing the integrity of the shank. The Job Knob also magnetically stays with the tank in use until the time of exchange; where it can be easily slid onto the new tank valve until the next exchange.
Always have a tool to open your tank, and most importantly it will be right were you left it...on the tank!

Like the other reviewer, the product does it's job but the form of the knob is hard on the hands and the bottle is difficult to open if the valve is closed off tightly, A slightly larger knob and and a rubberized coating would help. As an added tip I wanted to make sure the knob didn't get lost so I used aircraft cable to secure the knob by drilling a hole through the knob face and threading the cable through the hole to use it as a tether and securing the other cable end to my torch tote. all in all it works great.

I like the way it fits and the magnetic hold. If it was just a little bit bigger around, it would make turning on some of the tighter tanks easier and easier to grip.
