Daresaw

Daresaw is a fictional autonomous cutting tool used in speculative fiction, educational simulations, and maker-culture discussions to illustrate issues around automated tools and safety. In most depictions, a Daresaw is enclosed in a protective housing and connected to an AI control module that handles blade engagement, speed control, and path planning. The device typically features a modular blade system, varying from fine-tooth blades for precision work to heavy-duty blades for larger cuts, and a sensor suite that includes optical, force, and proximity sensors. Safety is a central theme; conventional features include interlocks, an emergency-stop switch, soft-start routines, and a kill-switch that disables the unit if faults are detected or human operators are within a forbidden zone.

While purely fictional, Daresaws are often used in demonstrations of safe automation design, including fail-safe behavior, safe operating procedures, and human-robot interaction. Origin and usage: The concept emerged in online maker forums and educational blogs in the late 2010s as a thought experiment to discuss risk, accountability, and control in autonomous tools. It has since appeared in classroom simulations and some science-fiction narratives as a plot device to explore how automated tools shape work practices and environmental impact.
