- 4. The circular saw as set forth in claim 1 wherein the saw blade has opposite faces, wherein one of the opposite faces of the saw blade faces a substantial portion of said circular saw, and wherein, in the optimal cutting position, the operator can view the one of the opposite faces of the saw blade as the saw blade cuts the workpiece.
- 5. The circular saw as set forth in claim 1 wherein, when the operator holds said auxiliary handle with the other hand, the operator's other hand and said auxiliary handle do not obscure the operator's view of the saw blade as the saw blade cuts the workpiece.
- 6. The circular saw as set forth in claim 1 wherein said auxiliary handle is supported by said shoe plate.
- 7. The circular saw as set forth in claim 6 and further comprising a support post mounted on said shoe plate, wherein said auxiliary handle is supported on said support post, and wherein said support post and said auxiliary handle are arranged so that, in the optimal cutting position, the operator can view the saw blade as the saw blade cuts the workpiece.
- 8. The circular saw as set forth in claim 7 wherein, when the operator holds said auxiliary handle with the other hand, the operator's other hand and said auxiliary handle do not obscure the operator's view of the saw blade as the saw blade cuts the workpiece.
- 9. The circular saw as set forth in claim 7 wherein said support post and said housing are arranged to provide therebetween a space, and wherein, in the optimal cutting position, the operator can view the saw blade cutting the workpiece through said space.
- 10. The circular saw as set forth in claim 1 wherein the operator views the saw blade as the saw blade cuts the workpiece along a line-of-sight, wherein the saw blade defines a cutting plane, wherein a bevel angle is defined between the cutting plane of the saw blade and a surface of the workpiece, wherein said circular saw further comprises a bevel angle adjustment assembly pivotally connecting said shoe plate to said housing so that the bevel angle is adjustable, said bevel angle adjustment assembly including an indicator for indicating the bevel angle, wherein said indicator is arranged so that, in the optimal cutting position, the operator can view the indicator along generally the line-of-sight of the saw blade as the saw blade cuts the workpiece.
- 11. A circular saw comprising:
a motor for rotatably driving a saw blade about an axis to cut a workpiece, the saw blade defining a cutting plane, a bevel angle being defined between the cutting plane of the saw blade and a surface of the workpiece; a housing supporting said motor; a shoe plate supporting said circular saw on the workpiece to be cut, said shoe plate being pivotably connected to said housing to adjust the bevel angle; a main handle supported by said housing; an auxiliary handle supported by said housing; and an indicator for indicating the bevel angle, said indicator being supported by at least one of said housing and said shoe plate; wherein, in a cutting position, while cutting the workpiece with the saw blade, an operator holds said main handle with one hand and said auxiliary handle with the other hand, and wherein said indicator is supported so that, in the cutting position, the operator can view said indicator.
- 12. The circular saw as set forth in claim 11 wherein said indicator includes
a first indicator member supported on one of said housing and said shoe plate, and a plurality of second indicator members supported on the other of said housing and said shoe plate, wherein said first indicator member is alignable with one of said plurality of second indicator members to indicate a first bevel angle, and wherein said first indicator member is alignable with another of said plurality of second indicator members to indicate a second bevel angle.
- 13. The circular saw as set forth in claim 12 wherein said first indicator member is supported by said shoe plate and said plurality of second indicator members are supported by said housing.
- 14. The circular saw as set forth in claim 10 wherein the operator has a line-of-sight of the saw blade as the saw blade cuts the workpiece, and wherein said indicator is arranged so that, in the cutting position, the operator can view the indicator along generally the line-of-sight of the saw blade as the saw blade cuts the workpiece.
- 15. The circular saw as set forth in claim 14 wherein the saw blade has an inward face and an outward face, and wherein, in an optimal cutting position, the operator can view the inward face of the saw blade along the line-of-sight as the saw blade cuts the workpiece.
- 16. A circular saw comprising:
a motor for rotatably driving a saw blade about an axis to cut a workpiece, the saw blade defining a cutting plane, a bevel angle being defined between the cutting plane of the saw blade and a surface of the workpiece; a housing supporting said motor; a shoe plate supporting said circular saw on the workpiece to be cut, said shoe plate being pivotably connected to said housing to adjust the bevel angle; a main handle supported by said housing; an auxiliary handle supported by said housing; and an indicator for indicating the bevel angle, said indicator being supported by at least one of said housing and said shoe plate; wherein, in a cutting position, while cutting the workpiece with the saw blade, an operator holds said main handle with one hand and said auxiliary handle with the other hand, wherein said main handle, said auxiliary handle and said indicator are arranged so that, in the cutting position, the operator can view the saw blade as the saw blade cuts the workpiece and can view said indicator.
- 17. The circular saw as set forth in claim 16 wherein the saw blade has an inward face and an outward face, and wherein, in an optimal cutting position, the operator can view the inward face of the saw blade as the saw blade cuts the workpiece.
- 18. The circular saw as set forth in claim 17 wherein said housing defines an opening through which the inward face of the saw blade is visible, and wherein said circular saw further comprises air flow control means supported adjacent said opening and controlling a flow of air and debris created by the saw blade.
- 19. The circular saw as set forth in claim 16 wherein the operator views the saw blade as the saw blade cuts the workpiece along a line-of-sight, and wherein the operator views said indicator along generally the line-of-sight of the saw blade as the saw blade cuts the workpiece.
- 20. The circular saw as set forth in claim 19 and further comprising a bevel angle adjustment assembly pivotably connecting said shoe plate to said housing and operable to adjust the bevel angle, wherein, the operator can operate said bevel angle adjustment assembly while substantially maintaining the optimal cutting position.
