Devices With Cutting Chains and Link Configurations

A device incorporating a cutting chain comprising:

• a bar;
• and
• a plurality of links arranged in a chain along a chain path around the bar;
• wherein a first link comprises a hook that engages a recess of a second link, thereby coupling the first link and the second link and allowing the first link and the second link to pivot with respect to each other as the chain is driven around the bar;
• wherein the plurality of links further comprises a fin located at one of an outer surface of the hook or an outer surface of the recess and a pocket located at the other of the outer surface of the hook and the outer surface of the recess, wherein the fin is adapted to be positioned in the pocket.

A device incorporating a cutting chain comprising:

• a bar;
• and
• a plurality of links arranged in a chain along a chain path around the bar;
• wherein a first link comprises one or more cutting teeth positioned along a first lateral side of the first link with no cutting teeth positioned along a second lateral side of the first link, and the second link comprises one or more cutting teeth positioned along a second lateral side of the second link with no cutting teeth positioned along a first lateral side of the second link.

A device incorporating a cutting chain comprising:

• a bar;
• and
• a plurality of links arranged in a chain along a chain path around the bar;
• wherein a first link comprises a protruding tab extending from a first adjacent link side of the first link, and the second link comprises an indented socket in a second adjacent link side of the second link;
• wherein the protruding tab of the first link is adapted to be positioned in the indented socket of the second link when the first link and the second link are longitudinally aligned.

A device incorporating a cutting chain comprising:

• a bar;
• and
• a plurality of links arranged in a chain along a chain path around the bar;
