NPR radio did the above piece today on a blade safety device called the Whirlwind which the inventor claims can be retrofitted to just about any existing table saw. The inventor is a retired engineer/hobby woodworker. Just as with the SawStop, the inventor says that the manufacturers of table saws have shown little interest in his device. NPR closed the piece by stating that the Consumer Product Safety Commission is in the process of writing new rules on table saw safety.
