  • Patent number: 9808939
    Abstract: An asymmetrical cutting tool has a partially cord-wrapped handle with a first handle panel, a second handle panel, and an intercheangeable overlay. The cutting tool further includes a folding blade, pivotably attached to the cord-wrapped/overlaid handle, and having a partially concave edge and a punch tip. The folding blade is operable to transition between a locked state and an unlocked state. Lock wear is compensated by dual eccentric thumb studs which act as a camshaft lobe to alter the position of the blade with respect to the lock while in the locked state. The partially cord-wrapped handle is configured to receive the folding blade when the blade transitions from the locked state into the unlocked state.
