Kershaw 3871 Amplitude with Speedsafe

Flipper - May be used on either manual or assisted opening knives. The "flipper" is a protrusion on the back of the blade that the user can pull back on, or flip, in order to move the blade easily out of the handle. Frame Lock - A portion of the handle( the knife frame) moves behind the blade to lock into position during use. This is a safety feature of the knife. Reversible - Pre-drilled holes in the handle enable the user to change either the tip position or the side on which the knife carries.
