Abstract
A saw chain includes a first tie strap, a first drive link coupled to the first tie strap, a second tie strap coupled to the first drive link, a second drive link coupled to the second tie strap, a third tie strap coupled to the second drive link, a first contoured cutting segment coupled to the first tie strap and having a first asymmetric profile, and a second contoured cutting segment coupled to the third tie strap and having a second asymmetric profile. The first contoured cutting segment and the second contoured cutting segment are oriented such that the first asymmetric profile is symmetric with the second asymmetric profile across the second drive link.

A saw chain comprising:
- a first tie strap;
- a first drive link coupled to the first tie strap;
- a second tie strap coupled to the first drive link;
- a second drive link coupled to the second tie strap;
- a third tie strap coupled to the second drive link;
- a first contoured cutting segment coupled to the first tie strap and having a first asymmetric profile;
- and
- a second contoured cutting segment coupled to the third tie strap and having a second asymmetric profile, wherein the first contoured cutting segment and the second contoured cutting segment are oriented such that the first asymmetric profile is symmetric with the second asymmetric profile across the second drive link.
A saw chain comprising:
- a first tie strap;
- a contoured cutting segment coupled to the first tie strap, the contoured cutting segment comprising:
- a first asymmetric tooth;
- and
- a second asymmetric tooth oriented such that the second asymmetric tooth is symmetric with the first asymmetric tooth across a center of the contoured cutting segment.
A saw chain comprising:
- a first tie strap;
- a first drive link coupled to the first tie strap;
- a second tie strap coupled to the first drive link;
- a second drive link coupled to the second tie strap;
- a third tie strap coupled to the second drive link;
- a first contoured cutting segment coupled to the first tie strap, the first contoured cutting segment having a first plurality of asymmetric teeth;
- and
- a second contoured cutting segment coupled to the third tie strap, the second contoured cutting segment having a second plurality of asymmetric teeth, the second plurality of asymmetric teeth symmetric with the first plurality of asymmetric teeth across the second tie strap.
