Saw will not cut your fingers!!

Before reading watch the video above. SawStop is a safety feature incoporated in a saw machine that immediately stops and retracts a spinning saw blade if it comes in contact with anything that even remotely resembles your finger. Whew..!
If you saw the video the hot dog just got a minor scratch because of the human finger, when you are using one of these - you don’t worry about looking for a replacement finger.

How it works ?
The SawStop safety system includes an electronic detection system that detects when a person contacts the blade. The system induces an electrical signal onto the blade and then monitors that signal for changes. The human body has a relatively large inherent electrical capacitance and conductivity which cause the signal to drop when a person contacts the blade. Wood has a relatively small inherent capacitance and conductivity and does not cause the signal to drop. A fast-acting brake stops the blade when contact is detected.
