Yes,marline spikes and how I love 'em.Boatswain's Mates in the U.S. Navy still carry an eight inch spike.They are used for all manner of uses from stirring coffee to opening screw pin shackles.But alas,in todays Navy they are seldom used for thier true purpose of splicing wire rope and line or knot work.Regretfully a lot of the old timers that did that work are no longer around.Now younger sailors are more interested in computers than good ole seamanship...
