The Tool Cart is modeled after the rolling metal tool chests commonly found in automotive garages and workshops. These mobile cabinets became popular in the mid-20th century as car repair grew more specialized and mechanics needed organized, movable storage for heavy tools. The bright red paint and metal drawer handles — now iconic in brands like Snap-on and Craftsman — became a visual symbol of professional workshop equipment, which is exactly the look the Animal Crossing Tool Cart captures.
This tool cart available on Amazon is the closest I've found to the Animal Crossing version. Like the in-game version it has two tool drawers with silver colored handles, wheels for rolling it, and a black top (which in the case of the IRL version expands to provide workspace).
