The key is not to rub your skin across the edge of the blade or vice versa. Avoid all laterial movement.



I can easily grab a razor blade by the cutting edges as long as the pressure is kept perpendicular to the edge. As soon as there is any lateral movement along the edge of the blade, however, there will be blood.



The tabbed ends are die cut. Although not as sharp as the honed edge, they often have a jagged burr that can be just as dangerous. Thus, you have to follow the same procedure you do with the honed edge. All pressure has to be perpendicular to the tab with no lateral movement whatsoever.
