There isn't a good indication of scale in the pictures, but those look like fire-hydrant wrenches. TLC0028 might be doing dual duty as a chipping hammer. Maybe it's for chipping through multiple fire hydrant repaintings to open a fire hydrant that hasn't been opened in decades.

Most 5-sided tools like those were for fire hydrants.

These wrenches have to be to access electric utility vaults, or fire hydrants. That’s the only place you’ll fine penta-head bolts.

The tools are used to remove/replace the 5 sided bolt which holds a cover over a shut off valve in the ground for shutting off the main water supply to many homes or businesses. It is usually referred to as a Buffalo Box. The 5 sided size bolt was a tamper proof item to keep most people from turning back on their water after a municipality had turned it off for non payment.

The tool on the left (TLC0028) is a chipping hammer and wrench to turn off and on oxy accetlyne tanks for cutting steel. The tool on the right (TLC0029) is same thing but just turns on or off the bottles.

They came with large wood stoves; some air vents had bolts to open and close. The vents down at the ash door were slides, so the point was used to push the vent open or closed. A tap with the hammer would get the door to slide when hot. I still use one like the photo on the right (TLC0029). Even the early gas heaters used something like the one on the left (TLC0028). When I worked at Yellowstone, the modern 1930s heater and cook stoves had these tools hanging on the wall, but with longer handles than the one on the left (TLC0028).

Fire hydrants require 5 sided wrenches. Any I have seen had longer handles for more leverage though.

Mueller is still in business today manufacturing everything from small shut off water valves to large city water hydrants. Their 2007 catalog, page 7.28 Curb Boxes-Optional Equipment, has the ductile iron version of TLC0028 listed as H-10323 Pentagon Key. This tool is used for operating the screws of Mueller and Buffalo type curb boxes or repair lids. One end is pointed for digging ice or dirt away from lid of box. The other end is a hammer head. Fits standard water works pentagon."
