Abstract
A cutting tool is provided which may include a first blade and a second blade, where the first blade is coupled to the second blade at a first pivot point, where the first blade defines a cam follower and pivots relative to the second blade about a first pivot axis through the first pivot point; and a lever pivotably coupled to the second blade at a second pivot point, where the lever defines a cam surface and pivots relative to the second blade about a second pivot axis through the second pivot point, where the second blade is driven toward the first blade in response to the lever being advanced toward the first pivot point and the cam follower translating along the cam surface.
Claims18
A cutting tool comprising:
- a first blade and a second blade, wherein the first blade is pivotably coupled to the second blade at a first pivot point, wherein the first blade is configured to pivot relative to the second blade about a first pivot axis through the first pivot point;
- and
- a lever pivotably coupled to the second blade at a second pivot point, wherein the lever is configured to pivot relative to the second blade about a second pivot axis through the second pivot point,
- wherein one of the first blade and the lever defines a cam surface, wherein the one of the first blade and the lever not defining a cam surface defines a follower, wherein in response to the lever being driven in a first direction, the follower is configured to move relative the cam surface, closing the first blade with respect to the second blade to form a cutting nip,
- wherein the second blade is coupled to the lever with a fastener defining an axis along the first pivot axis, wherein the first blade defines an arcuate slot, and wherein in response to the first blade closing with respect to the second blade, the fastener is configured to translate within the arcuate slot.
A multipurpose tool comprising:
- a cutting tool translatable between a folded, stowed position relative to the multipurpose tool and a deployed position relative to the multipurpose tool, the cutting tool comprising:
- a first blade;
- a second blade,
- wherein the second blade is configured to pivot relative to the multipurpose tool about a first axis between the folded, stowed position and the deployed position, and
- wherein the first blade is configured to pivot relative to the multipurpose tool about the first axis between the folded, stowed position
- and the deployed position;
- a lever pivotally coupled to the second blade and pivotable relative to the second blade about a second axis different from the first axis, wherein in response to the cutting tool being disposed in the deployed position, driving the lever toward the multipurpose tool causes the first blade to pivot about the first axis toward the second blade;
- and a spring element, wherein the spring element is configured to engage a driving element of the first blade and biases the first blade away from the second blade.
A cutting tool comprising:
- a first blade and a second blade, wherein the first blade is pivotably coupled to the second blade at a first pivot point, wherein the first blade defines a cam follower and is configured to pivot relative to the second blade about a first pivot axis through the first pivot point;
- a lever pivotably coupled to the second blade at a second pivot point, wherein the lever defines a cam surface and is configured to pivot relative to the second blade about a second pivot axis through the second pivot point, wherein the second blade is configured to be driven toward the first blade in response to the lever being advanced toward the first pivot point and the cam follower translating along the cam surface;
- and
- a spring element, wherein the spring element is configured to engage a driving element of the first blade and biases the first blade away from the second blade.
