To expose the blade of the popular 10493 tool, simply squeeze the trigger mechanism and you’re ready to go. A blade-lock switch prevents accidental blade exposure. As with all Slice blades, the installed blade has a finger-friendly edge that’s specifically engineered to be safe to the touch and lower the risk of lacerations. In addition, the zirconium oxide blades lasts up to 11x longer than metal blades and never rusts. Other convenient features include an integrated lanyard hole and easy, no-tool blade change.
