Tesla wasn't just a random surname - it's literally the Slavic word for 'adze', the carpentry tool with a perpendicular blade used for shaping timber.
The etymology traces back through Proto-Slavic *tesla* to an Indo-European root meaning 'to hew'. The word exists across Slavic languages: Serbian/Croatian tesla, Russian tesló, Bulgarian teslá, Slovene tésla. It was an occupational surname - you were called Tesla if you worked with the adze.
Nikola Tesla, born 1856 in Smiljan, inherited this craftsman's name. His ancestor supposedly got the surname due to prominent teeth (which resembled the tool's shape). So the guy who invented the AC induction motor and laid the foundation for modern electrical grids literally carried the name of a wood-shaping tool.
The technical parallel is kind of perfect: one Tesla carved physical structures, another shaped electromagnetic fields. The magnetic flux density unit (1 tesla = 1 weber per square meter) and the EV company both trace back to a tool for precision material work.
Not borrowed, not metaphorical - just a straight line from carpentry tool → family name → electrical pioneer → modern tech brand. The name was always about shaping things, whether wood or magnetic fields.
