Abstract
An adjustable multi-blade knife is disclosed that includes a handle, a plurality of blades, and a blade spacing adjustment mechanism. The blades are oriented in parallel with each other and supported by the handle. The blade spacing adjustment mechanism is operable to cause movement of the second blade relative to the first blade while retaining a substantially parallel orientation with the first blade.
Claims20
An adjustable multi-blade knife comprising:
- a handle;
- a plurality of blades oriented in parallel with each other and supported by the handle, wherein each blade of the plurality of blades has a cutting edge that is linearly aligned with each other cutting edge;
- and
- a blade spacing adjustment mechanism, wherein activation of the blade spacing adjustment mechanism causes movement of at least one blade of the plurality of blades relative to another blade of the plurality of blades while retaining a substantially parallel orientation between the plurality of blades.

A multi-blade adjustable knife, comprising:
- a handle;
- a first blade extending a length of the handle;
- a second blade and a third blade positioned on opposite sides of and oriented in parallel with the first blade, wherein each of the second and third blades comprises a tip end and a second end that is opposite a respective tip end, and wherein each of the first, second, and third blades has a respective cutting edge that is linearly aligned with each other cutting edge;
- respective support members coupled to the second ends of the second and third blades, each support member having a screw interface;
- a blade spacing adjustment mechanism comprising:
- thumb screws positioned on opposite sides of the first blade;
- screw members extending from the thumb screws to the screw interfaces in the respective support members, wherein the screw members are rotatable by manipulating the thumb screws to screw into or unscrew from the screw interfaces;
- and
- an attachment member that couples the thumb screws and extends through an aperture in the second blade,
- wherein rotation of the thumb screws in a first direction causes the screw members to at least partially unscrew from the screw interfaces and the first and third blades to move away from the second blade while retaining a substantially parallel orientation with the first blade, and
- wherein rotation of the thumb screws in a second direction causes the screw members to at least partially screw into the screw interfaces and the first and third blades to move towards the second blade while retaining the substantially parallel orientation with the first blade.

A method of adjusting spacing between a first blade and a pair of second and third blades in a multi-blade adjustable knife, the method comprising:
- providing a multi-blade adjustable knife comprising:
- a handle,
- a first blade extending a length of the handle,
- a second blade and a third blade positioned on opposite sides of and oriented in parallel with the first blade, wherein each of the second and third blades comprises a tip end and a second end that is opposite a respective tip end, and wherein each of the first, second, and third blades has a respective cutting edge that is linearly aligned with each other cutting edge,
- respective support members coupled to the second ends of the second and third blades, each support member having a screw interface, and
- a blade spacing adjustment mechanism comprising thumb screws positioned on opposite sides of the first blade, elongated screw members extending from the thumb screws to the screw interfaces in the respective support members, and an attachment member that couples the thumb screws and extends through an aperture in the second blade;
- and
- rotating the thumb screws in a first direction to cause the screw members to at least partially unscrew from the screw interfaces, thereby moving the first and third blades away from the second blade while retaining a substantially parallel orientation with the first blade.
