During the first part of the 18th century, the blade heel and backspring of the navaja were cleverly altered to
provide a locking device for the blade. Pulling open the blade from the handle, the lock allowed the blade to rotate
into the fully open position, where it locked into position. The locking mechanism itself consisted of pinion teeth
(piñones or dientes) cut into the blade heel (talón de la hoja) that are engaged by a lug attached to either the
backspring or a separate spring-loaded metal latch as the knife is opened. The last pinion tooth serves to keep the
blade locked in its fully opened position. The ratcheting-tooth lock-blade navaja was commonly referred to as a
navaja de muelles or navaja de siete muelles. The metal-to-metal contact produces a distinctive clicking sound
when the blade is opened, and the navaja de muelles was popularly termed the carraca in consequence.
