The Job Knob
Many acetylene tanks do not come with a mechanism on the valve to open them, only a metal shank. 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 easily slide onto the new tank valve.
- Open/close valve with ease

Acetylene Safety Info:
These were copied and pasted directly from OSHA.gov and are open to interpretation.
Cylinders not having fixed hand wheels shall have keys, handles, or nonadjustable wrenches on valve stems while these cylinders are in service. In multiple cylinder installations only one key or handle is required for each manifold.
A hammer or wrench shall not be used to open cylinder valves. If valves cannot be opened by hand, the supplier shall be notified.
Where a special wrench is required it shall be left in position on the stem of the valve while the cylinder is in use so that the fuel-gas flow can be quickly turned off in case of emergency. In the case of Mani folded or coupled cylinders at least one such wrench shall always be available for immediate use.
