Until the Kershaw Rainbow Centofante came along only the Chive and the Leek were offered with a titanium oxide coating, which is responsible for the rainbow color of the knife. What makes the Centofante so popular was that it was cooperatively designed by Frank Centofante and Ken Onion. This rainbow colored version of the Kershaw Centofante comes with a fast draw sheath that is open at the top, giving you the opportunity to show it off while its riding on your belt or pocket. You think the pictures are good? Wait 'til you see this knife in person!
