Claims
- 1. A knife comprising an outer surface adapted to be gripped by the hand of a user, wherein said outer surface comprises:
- (a) a plurality of first discrete protuberances, said first protuberances comprising at least one planar surface portion that is angled in a first planar direction relative to said outer surface, said planar surface having at least one apex associated with each of said first protuberances, said apexes of said first discrete protuberances progressively increasing in height relative to said outer surface as the distance from a preselected line or point on said outer surface increases; and
- (b) a plurality of second discrete protuberances, said second protuberances comprising said planar surface portion that is angled in a second planar direction relative to said outer surface, said planar surface having at least one apex associated with each of said second protuberances, said apexes, of said second discrete protuberances progressively increasing in height relative to said outer surface as the distance from a preselected line or point on said outer surface increases, wherein said second planar direction is different than said first planar direction to provide slip resistance in at least two distinct directions.
- 2. The knife of claim 1, wherein said knife is a folding knife.
- 3. The knife of claim 1, wherein said first and second protuberances comprise at least one common apex.
- 4. The device of claim 1, wherein said planar surface is shaped substantially like an arrowhead.
- 5. The device of claim 1, wherein said planar surface is substantially triangular shaped.
- 6. The knife of claim 1, further comprising a clip interconnected to said knife's outer surface for removably interconnecting said knife to an object.
- 7. The device of claim 1, wherein said outer surface material is comprised of at least one plastic or rubber material.
- 8. A knife comprising an outer surface adapted to be gripped by the hand of a user, said outer surface comprising:
- a multiplicity of first discrete protuberances oriented in a series of rows and columns, said rows originating at a preselected line or point on said outer surface, each of said protuberances comprising:
- a planar surface oriented in a non-parallel plane to said outer surface having at least one apex which is substantially shaped like an arrowhead, wherein said apex and said surface are slip resistant to a user of said knife in two distinct directions; and
- wherein the height of each of said apex from said outer surface progressively increases as the distance from said preselected point increases.
- 9. The knife of claim 8, wherein the height of said apex from said outer cover progressively increases as the distance from said preselected point increases.
- 10. The knife of claim 8, further comprising a multiplicity of second discrete protuberances extending in a second direction from said preselected point and further oriented in a series of rows and columns.
- 11. The knife of claim 8, wherein said preselected point is substantially centered on said outer surface.
