Cutlery having improved gripping ergonomics
View Patent ↗A knife for cutting food products having a proximal end, a distal end and a length defined therebetween. The knife includes a blade portion having a cutting edge and a spine disposed on a top side of the blade portion and generally opposed to the cutting edge. The knife includes a handle portion disposed proximal of the blade portion with a top surface and a bottom surface, a first end proximal to the blade portion and a second end distal to the blade portion. The handle portion includes a bolster section with at least a first thickness, a first lateral sidewall and a second lateral sidewall. The bolster section is disposed at the first end of the handle portion and adjacent to the blade portion. The first sidewall of the bolster section includes an arcuate proximal bolster boundary defined by a curvilinear ridge extending downwardly toward the blade portion from a point proximate the top surface of the handle portion. The first sidewall of the bolster section also includes an arcuate distal bolster boundary being defined by a curvilinear ridge extending downwardly toward the blade portion from a point proximate the bottom surface of the handle portion. A portion of the curvilinear ridge defining the arcuate proximal bolster boundary is spaced a distance along the length of the knife from a portion of the curvilinear ridge defining the arcuate distal boundary. A surface depression is formed in at least one of the first lateral sidewall and the second lateral sidewall, the surface depression being disposed between the curvilinear ridge defining the arcuate proximal bolster boundary.
1. A knife having a proximal end, a distal end and a length defined therebetween, the knife comprising:
a blade portion having a cutting edge and a spine, the spine being disposed on a top side of the blade portion and generally opposed to the cutting edge;
a handle portion disposed proximal of the blade portion, the handle portion having a top surface and a bottom surface, a first end proximal to the blade portion and a second end distal to the blade portion;
the handle portion further comprising a bolster section, the bolster section having at least a first thickness, a first lateral sidewall and a second lateral sidewall, the bolster section being disposed at the first end of the handle portion and adjacent to the blade portion, the first sidewall of the bolster section comprising:
an arcuate proximal bolster boundary, the arcuate proximal bolster boundary being defined by a curvilinear ridge extending downwardly toward the blade portion from a point proximate the top surface of the handle portion and an arcuate distal bolster boundary, the arcuate distal bolster boundary being defined by a curvilinear ridge extending downwardly toward the blade portion from a point proximate the bottom surface of the handle portion, wherein a portion of the curvilinear ridge defining the arcuate proximal bolster boundary is spaced a distance along the length of the knife from a portion of the curvilinear ridge defining the arcuate distal boundary; and
a surface depression formed in at least one of the first lateral sidewall and the second lateral sidewall, the surface depression being disposed between the curvilinear ridge defining the arcuate proximal bolster boundary.
2. The knife of claim 1 , wherein the cutting edge is serrated.
3. A method of grasping a knife for slicing, the method comprising:
providing a knife having a proximal end, a distal end and a length defined therebetween, the knife comprising a blade portion having a cutting edge and a spine, the spine being disposed on a top side of the blade portion and generally opposed to the cutting edge; a handle portion disposed proximal of the blade portion, the handle portion having a top surface and a bottom surface, a first end proximal to the blade portion and a second end distal to the blade portion; the handle portion further comprising a bolster section having at least a first thickness, a first lateral sidewall and a second lateral sidewall, the bolster section being disposed at the first end of the handle portion and adjacent to the blade portion, the first sidewall of the bolster section comprising an arcuate proximal bolster boundary, the arcuate proximal bolster boundary being defined by a curvilinear ridge extending downwardly toward the blade portion from a point proximate the top surface of the handle portion and an arcuate distal bolster boundary, the arcuate distal bolster boundary being defined by a curvilinear ridge extending downwardly toward the blade portion from a point proximate the bottom surface of the handle portion, wherein a portion of the curvilinear ridge defining the arcuate proximal bolster boundary is spaced a distance along the length of the knife from a portion of the curvilinear ridge defining the arcuate distal boundary;
placing a thumb of a first hand on a first side of a bolster between the arcuate proximal bolster boundary and the arcuate distal bolster boundary;
placing an index finger of the first hand on a second side of the bolster between the proximal boundary and the distal boundary, the second side of the bolster being opposite of the first side of the bolster and contacting a blunt surface of the bolster; and
wrapping at least one of the remaining fingers of the first hand around a handle portion of the knife.
4. A knife having a proximal end, a distal end and a length defined therebetween, the knife comprising:
a blade portion having a cutting edge and a spine, the spine being disposed on a top side of the blade portion and generally opposed to the cutting edge;
a handle portion disposed proximal of the blade portion, the handle portion having a top surface and a bottom surface;
a bolster portion having at least a first thickness, a first lateral sidewall and a second lateral sidewall, the bolster being disposed at a position along the length of the knife between the blade portion and the handle portion, the first sidewall of the bolster comprising:
an arcuate proximal bolster boundary, the arcuate proximal bolster boundary being defined by a curvilinear ridge extending downwardly toward the blade portion from a point proximate the top surface of the handle portion and an arcuate distal bolster boundary, the arcuate distal bolster boundary being defined by a curvilinear ridge extending downwardly toward the blade portion from a point proximate the bottom surface of the handle portion, wherein a portion of the curvilinear ridge defining the arcuate proximal bolster boundary is spaced a distance along the length of the knife from a portion of the curvilinear ridge defining the arcuate distal boundary; and
a surface depression formed in at least one of the first lateral sidewall and the second lateral sidewall, the surface depression being disposed between the curvilinear ridge defining the arcuate proximal bolster boundary.
