Anything is a hammer to an electrician, including their fists.

Truly is one of the most versatile tools to own.

Oh, they forgot the dildo hammer too.

You know, sometimes you got to hammer the thing in all the way.
(Don't worry if you miss and accidentally hit the balls, it's fine.)

It's there under "power hammer"

Yeah, this is how shields and armor were made, as planishing doesn't thin out the metal so much.

Also missing is MC.

Omg DOUBLE PEEN

My time has come.

I'm what the aerospace industry calls a "surface enhancement engineer." A fancy way of calling me a peener. I mostly work with CNC air blast shot peening machines but the principle is essentially the same as a ball peen hammer.

Basically, hitting metal with hard ball causes little dimples to form on the surface of your work piece. Hit it a shit load of times and you get dimples all over. At the end of the day all those dimples help prevent stress fractures from forming.

I like you

Peenetration

Engineers hammer is used to smack things and see what happens. You're not meant to drive nails or shape metal with it, but it's used to do inspections.

For example, a structural engineer inspecting a truss bridge might go and smack every stringer or strut near the rivet to the beam to see what happens. If the strut jiggles a bit, then the rivet has loosened and might need to be replaced.

If a bit of steel is heavily rusted, the engie might belt it really hard to see if it breaks due to deep corrosion, or if it's just surface rust.

The sound you get from smacking a bit of steel can also tell you about the material, good steel will bong and reverb, bad steel will be dull and not reverb.
