Claims
- 1. A tool capable of severing sheet material at a first uniform predetermined distance from a first line of intersection of a first surface and second surface forming an "inside" edge with an angle therebetween of less than 180.degree., and capable of severing sheet material at a second uniform predetermined distance from a second line of intersection of a third and fourth surface forming an "outside" edge with an angle therebetween of greater than 180.degree., said tool comprising:
- a body with a front edge adapted to slidingly guide the tool along said first surface or said third surface and a substantially flat bottom surface adapted to slidingly guide the tool along said second surface,
- cutting means extending beyond said front edge of said body, which is maintained by said front edge and said flat surface of said body at said first predetermined distance from said first line of intersection,
- a removable spacer plate and means for engaging said removable spacer plate at a predetermined position with respect to said body, wherein said spacer plate includes a lip with a substantially flat surface adapted to slidingly guide said tool along said fourth surface,
- so that when said removable spacer plate is disengaged from said body, said tool may be guided along said first and second surfaces by said front edge and said bottom surface, respectively, such that said cutting means severs sheet material applied to said first surface at said first uniform predetermined distance from said first line of intersection, and when said removable spacer plate is engaged with said body, said tool may be guided along said third and fourth surfaces by said front edge of said body and said lip of said spacer plate, respectively, so that said cutting means severs sheet material applied to said third surface at said second uniform predetermined distance from said second intersection.
- 2. A tool for severing sheet material at a uniform predetermined distance from the line of intersection of a first surface and a second surface, said tool comprising:
- a body with a front edge adapted to slidingly guide the tool along said first surface and a substantially flat bottom surface adapted to slidingly guide the tool along said second surface, and a substantially flat beveled surface extending between said bottom surface and said front edge adapted to slidingly guide the tool along said second surface at a predetermined angle with respect to said second surface,
- cutting means extending beyond said front edge of said body
- wherein when said tool is guided along said first and said second surfaces by said front edge and said bottom surface of said body, respectively, said cutting means severs sheet material applied to said first surface at said uniform predetermined distance from said line of intersection, and when said tool is guided along said first and said second surfaces by said said front edge and said beveled surface of said body, respectively, said cutting means severs sheet material applied across said line of intersection at said line of intersection.
- 3. The tool as set forth in claim 1 further comprising means for finely adjusting said cutting means to any point within the range defined by a fully retracted position wherein said cutting means does not extend beyond the front edge of said body and a fully extended position wherein said cutting means extends beyond said front edge of said body.
- 4. The tool as set forth in claim 1 further comprising abutment means for securely maintaining said cutting means at a predetermined relationship with respect to said body.
- 5. The tool as set forth in claim 1 wherein said tool is substantially symmetric about its transverse axis and said cutting means comprises a first cutting means on one side of said transverse axis and a second cutting means on the other side of said transverse axis.
- 6. The tool as set forth in claim 1 wherein said body includes a plurality of recesses to facilitate securely grasping the tool by hand.
- 7. A tool for severing sheet material at a uniform predetermined distance from the line of intersection of a first surface and a second surface, said tool comprising:
- a body with a front edge adapted to slidingly guide the tool along said first surface,
- cutting means extending beyond said front edge of said body, and
- a spacer plate secured at a predetermined position with respect to said body, wherein said spacer plate includes a front lip extending beyond said front edge of said body, said spacer plate having a substantially flat surface which is spaced apart from said cutting means a distance that defines said uniform predetermined distance and which is adapted to slidingly guide said tool along said second surface, so that when said tool is guided along said first and said second surfaces by said front edge and said flat surface of said spacer plate, respectively, said cutting means severs sheet material applied to said first surface at said uniform predetermined distance from said line of intersection.
- 8. The tool as set forth in claim 7 further comprising means for securing said spacer plate to said body in a second predetermined position wherein the distance between said lip and said cutting means defines a second predetermined distance which differs from said predetermined distance.
- 9. The tool as set forth in claim 7 further comprising means for finely adjusting said cutting means to any point within the range defined by a fully retracted position wherein said cutting means does not extend beyond the front edge of said body and a fully extended position wherein said cutting means extends beyond said front edge of said body.
- 10. The tool as set forth in claim 7 further comprising abutment means for securely maintaining said cutting means at a predetermined relationship with respect to said body.
- 11. The tool as set forth in claim 7 wherein said tool is substantially symmetric about its transverse axis and wherein said cutting means comprises a first cutting means on one side of said transverse axis and a second cutting means on the other side of transverse axis.
- 12. The tool as set forth in claim 7 wherein said body includes a plurality of recesses to facilitate securely grasping the tool by hand.
- 13. A tool for severing sheet material at a uniform predetermined distance from the line of intersection of a first surface and a second surface, said tool comprising:
- a body with a front edge adapted to slidingly guide the tool along said first surface,
- cutting means extending beyond said from edge of said body, and
- guidance means comprised of a front lip extending beyond said from edge of said body, said front lip having a substantially flat surface which is spaced apart from said cutting means a distance that defines said uniform predetermined distance and which is adapted to slidingly guide said tool along said second surface, so that when said tool is guided along said first and said second surfaces by said from edge and said flat surface of said from lip, respectively, said cutting means severs sheet material applied to said first surface at said uniform predetermined distance from said line of intersection.
