Claims
- 1. A method of cutting a building sheet having at least one guide groove formed into a face of the building sheet, wherein the guide groove is formed at a first depth such that the application of force at the guide groove will not result in the board breaking, comprising:scoring the building sheet at a desired location on a surface of the sheet, the scoring of the sheet forming a score mark in the surface, wherein the score mark has a depth greater than the first depth such that the application of force at the score mark will result in the board breaking; and bending the sheet along the score mark to break the sheet.
- 2. The method of claim 1, wherein the sheet is scored using a knifepoint.
- 3. The method of claim 1, wherein the sheet is scored such that the score mark lies within and substantially along the guide groove.
- 4. The method of claim 1, wherein the sheet is scored such that the score mark lies substantially outside the guide groove.
- 5. The method of claim 4, wherein the score mark cuts across at least one guide groove.
- 6. The method of claim 5, wherein the score mark extends diagonally across the building sheet.
- 7. The method of claim 1, wherein the first depth is less than about 25% of the thickness of the building sheet.
- 8. The method of claim 7, wherein the first depth is less than about 15% of the thickness of the building sheet.
- 9. The method of claim 1, wherein the first depth is between about 0.01 to 0.06 inch and the thickness of the building sheet is about ¼ inch.
