ABSTRACT:
In one embodiment, a folding knife comprises a handle portion and first and second nesting blades pivotally coupled to the handle portion for pivoting movement between respective open and closed positions. The second blade in one embodiment is formed with a recess or notch which is sized and shaped to receive the first blade, allowing both blades to pivot within a common plane. The knife can also include a locking mechanism that is operable to retain the blades against pivoting movement when the blades are in their respective open positions. In particular configurations, the locking mechanism comprises a resilient locking arm configured to lock both blades in their open positions or first blade alone in its respective locking position. In certain embodiments, a folding tool comprises plural nesting tool elements other than knife blades.
