This John Kubasek custom 4" Hawkbill knife is a stellar flipper. It features a hand satin finished CPM-154 steel blade with a beautifully filed spine. The titanium liners are outfitted with carbon fiber scales and a tip-down carry pocket clip. The back scale acts as a stop for the liner lock tab. This Hawkbill knife has great feel, action and lockup thanks in part to the ball bearing flipper. This Hawkbill Flipper is collection and carry worthy quality you'll love.
