- 6. The saw blade according to claim 1, wherein an expansion slot is connected with said gullet, said expansion slot having a neck and an ellipsoidal or oval shaped body.
- 7. The saw blade according to claim 1, wherein said saw blade is a wood cutting blade.
- 8. The saw blade according to claim 1, wherein said gullet extends below said tooth, said bottom being at a distance from the blade center of about eighty to ninety-five (80-95%) percent of the radius of the blade.
- 9. The saw blade according to claim 1, wherein said bottom is at a distance at about ninety (90%) percent of the radius of the blade.
- 10. The saw blade according to claim 1, wherein said tooth is soldered or brazed onto said blade.
- 11. The saw blade according to claim 1, wherein said tooth is a carbide tooth secured to said blade.
