Abstract
An apparatus may determine the quality of a fencing blade. The apparatus may include an electrical current source; a fencing blade to be tested for quality; two electrical cables, each connected between the electrical current source and the fencing blade so as to cause current from the current source to travel through at least a portion of the fencing blade; and a magnetic field sensor in sufficient proximity to the fencing blade so as to enable the magnetic field sensor to detect a magnetic field generated by the fencing blade when the current passes through the fencing blade.
