A specific style of Improvised Weapon when a tradesperson uses the tools of their trade as combat weaponry. Iconic tools are preferred, because they demonstrate the character's proficiency with the tool, despite the current use as a weapon. It serves the dual purpose of making the combatant's style unique and reminding the audience what career they're from.
In the real world, most occupations have tools of the trade that are used entirely for utilitarian purposes. In the fictional world, these master craftspeople can wield these tools with deadly force. The firefighter who normally only uses the axe to bash in doors now bashes in skulls. The painter's brush spills blood with every stoke. The mechanic's wrench now breaks ribs.
Note that for this trope, "tools" are distinct from "weapons"; a weapon's primary purpose is to hurt people, while a tool intends some mechanical effect. A police club is a weapon, while the handcuffs are tools to restrain. Characters using these tools also count as an Improbable Weapon User.
Inversions (weapons used as tools) would be Improbable Use of a Weapon or Mundane Utility. When characters grab everyday tools (but not tools of their career) to fight with, it's Gardening-Variety Weapon. For skill with tools acquired as part of a character's backstory, see Chekhov's Hobby and Workplace-Acquired Abilities.
This is a Super-Trope to I Know Madden Kombat, where athletes use their sports equipment to fight, and Musical Assassin, where musicians use their instruments of death. Overlaps with Chef of Iron, a trope about cooks being fighters, even if they don't use their cooking implements to fight.
