How Can a Saw Know What It’s Cutting?

The video discusses the dangers of table saws, which are responsible for many accidental amputations. It highlights the invention of the SawStop technology in 1999, which detects human flesh and stops the blade in milliseconds to prevent injuries. The technology uses a weak electrical current to differentiate between wood and flesh. Despite its effectiveness, SawStop remains proprietary, and most saws lack this feature. The video emphasizes the importance of caution and common sense when using saws, as human reflexes are insufficient to prevent accidents.
