Abstract

A saw blade for rectilinear cutting motion, especially of a manually operated saw, comprising, at one longitudinal edge, at least a first section of a series of teeth formed at least at an end of the saw blade, and a second section of a series of teeth formed essentially in the middle of the saw blade, the tooth geometry, tooth configuration, tooth dimension, and/or the like of the first section of the tooth series differing from the tooth geometry, tooth configuration, tooth dimension, and/or the like of the second section of the tooth series in such a way that the cutting volume of a fixed number of teeth of the first section of the tooth series is smaller than the cutting volume of the same number of teeth of the second section of the tooth series.

Claims

1. A saw blade for rectilinear cutting motion, especially of a manually operated saw, comprising, at one longitudinal edge, at least a first section of a series of teeth formed at least at an end of the saw blade, and a second section of a series of teeth formed essentially in the middle of the saw blade, the tooth geometry, tooth configuration, tooth dimension, and/or the like of the first section of the tooth series differing from the tooth geometry, tooth configuration, tooth dimension, and/or the like of the second section of the tooth series in such a way that the cutting volume of a fixed number of teeth of the first section of the tooth series is smaller than the cutting volume of the same number of teeth of the second section of the tooth series.

2. The saw blade as claimed in claim 1, wherein the tooth pitch of the first section of the tooth series is greater than the tooth pitch of the second section of the tooth series.

3. The saw blade as claimed in claim 2, wherein the tooth pitch of the first section of the tooth series is greater by at least one tooth per inch than the tooth pitch of the second section of the tooth series.

4. The saw blade as claimed in any claim 1, wherein the first section of the tooth series at least at one end of the saw blade extends across at least ⅙

of the total length of the saw blade.

5. The saw blade as claimed in claim 1, wherein the length of the second section of the tooth series corresponds to at least three times the length of the first section of the tooth series.

6. The saw blade as claimed in claim 1, wherein the tooth height of the first section of the tooth series is smaller than the tooth height of the second section of the tooth series.

8. The saw blade as claimed in claim 2 wherein the tooth pitch of the first section of the tooth series is greater by at least two teeth per inch than the tooth pitch of the second section of the tooth series.

9. The saw blade as claimed in claim 2 wherein the tooth pitch of the first section of the tooth series is greater by at least three teeth per inch than the tooth pitch of the second section of the tooth series.

10. The saw blade as claimed in claim 2 wherein the tooth pitch of the first section of the tooth series is greater by one third than the tooth pitch of the second section of the tooth series.

7. A saw comprising a saw blade comprising, at one longitudinal edge, at least a first section of a series of teeth formed at least at an end of the saw blade, and a second section of a series of teeth formed essentially in the middle of the saw blade, the tooth geometry, tooth configuration, tooth dimension, and/or the like of the first section of the tooth series differing from the tooth geometry, tooth configuration, tooth dimension, and/or the like of the second section of the tooth series in such a way that the cutting volume of a fixed number of teeth of the first section of the tooth series is smaller than the cutting volume of the same number of teeth of the second section of the tooth series.
