The old school ones only did one thing, open hydrants, the new one we had were basically just a huge crescent wrench head welded on to a solid steel pipe. You could use it for lots of stuff.
Neither of which would i want swung at me.
In addition to the concussion, both of the victim’s arms were broken as he tried to defend himself. Muhammad should simply be put down.
The fire hydrants I’ve seen use 5-sided ‘shafts’ for the valve control. A normal open end wrench, or even a 6 or 12 sided socket won’t fit it. A crescent wrench with parallel ‘faces’ won’t fit. (A pipe wrench will work, biting into the shaft).
This keeps the ordinary citizen from fooling with the hydrant.
A 5-sided ‘socket’ on the spanner will fit perfectly.
