The Kershaw Chive Knives were designed by custom knife maker and innovator Ken Onion. The Kershaw Chives have the patented Ken Onion Speed-Safe assisted opening mechanism. Speed-Safe is a torsion bar system that assists the blade to an open position, when activated by a push on the thumb stud, or the Index-Open blade extension.
The Kershaw Chive knives are available with stainless steel handles or aluminum handles. The stainless steel handled Chive knives are: Chive with original matte finish, High Polish Chive with all over mirror polished finish, Black Chive with all over black Boron-Carbide coat, and Rainbow Chive with all over rainbow Titanium Oxide coat. No two Rainbow Chives are exactly alike. The aluminum Chive knife is available with a pink handle.
