Filed:

Apr 23, 2009

Appl. No.:

12/429051

Inventors:

Edward Tate VanHoy - Abingdon VA, US

Assignee:

GB II Corporation - Tualatin OR

International Classification:

B26B 3/06

US Classification:

30159, 30153, 30158

Abstract:

In certain embodiments of the present disclosure, a folding knife has a biasing mechanism, such as a spring, that applies an opening force to the blade when the blade is in the closed, or folded, position (i. e. , the force of the spring creates a moment in the opening direction of the blade). The folding knife includes a latching mechanism that holds the blade in a closed and latched position against the opening force of the spring. To open the blade, manual pressure is applied to the upper edge of the blade (the edge opposite the sharpened edge) to move the blade slightly to a closed and unlatched position to release the blade from being held from the latching mechanism whereupon the blade is then free to pivot under the opening force of the spring.

Appl. No.:

11/435466

Inventors:

Edward VanHoy - Abingdon VA, US

International Classification:

B26B 1/04

US Classification:

030161000

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.

Appl. No.:

12/791748

Inventors:

Edward Tate VanHoy - Abingdon VA, US

International Classification:

B26B 1/04

US Classification:

30161

Abstract:

The present disclosure concerns embodiments of a folding knife having a locking mechanism for locking a blade in open and/or closed positions. The locking mechanism a first locking element on the blade and a corresponding second locking element on the handle that is adapted to engage the first locking element when the blade is in open and/or closed positions. The blade can be mounted on a leaf spring in the handle for pivotal movement relative to the handle between the open and closed positions. The leaf spring functions to support the blade and provide a biasing force that resiliently biases in a direction laterally toward the second locking element on the handle.
