A holder or carrier for continuously looped articles, e.g., chainsaw chains, is provided which prevents kinking and holds such articles in a secure, extended condition.

A reversible saw chain for a power chainsaw with a guide bar or blade may be a continuous loop of interconnected links with a plurality of spaced-apart cutting links and a plurality of connecting links. Each cutting link may include a first cutting surface facing a first direction and a second cutting surface facing a second direction that is opposite to the first direction, and a top plate extending between the first and second cutting surfaces and being not planar between these cutting surfaces. The top plate may have a first portion inclined inwardly away from the first cutting surface and a second portion inclined inwardly away from the second cutting surface and the first and second portions may be in a v-shaped configuration.

A saw chain includes a tie strap adapted to be pivotally connected to other links of the saw chain. The tie strap features an interior hole with a chamfered edge. An interior counterbore in the interior hole receives a barrel portion of a rivet. The rivet has two flanges extending from both sides of the barrel, each with a smaller diameter than the barrel, and each with chamfered corners in a transition area where the flanges meet the barrel. An exterior counterbore on an exterior surface of the tie strap receives a rivet head formed from one of the flanges, such that an exterior surface of the rivet head sits flush with the exterior surface of the tie strap.

The disclosure relates to a power tool separation device, in particular a hand-held power tool separation device, comprising at least one cutting unit which comprises at least two interconnected cutter support elements. At least two cutter support elements are interconnected by means of at least one connecting element of the cutting unit, and the connecting element is essentially flush with at least one outer surface of the at least two cutter support elements.

A chainsaw cutter for a chainsaw chain. The chainsaw cutter includes a cutter body having a pair of rivet holes extending through the cutter body. The chainsaw cutter further includes a cutting tooth coupled to and extending from an upper portion of the cutter body. The cutting tooth is configured to cut a workpiece during a cutting operation. Moreover, the chainsaw cutter includes a feed limiter coupled to and extending from the upper portion of the cutter body, and a gullet disposed between the cutting tooth and the feed limiter. The cutting tooth is formed on the cutter body by additive manufacturing.

A chainsaw chain includes a plurality of drive links, a plurality of cutters, and a plurality of rivets. Each drive link includes a drive link body, a pair of rivet holes extending through the drive link body, and a tang extending from the drive link body and configured to engage a drive element of a chainsaw. Each cutter includes a cutter body having a pair of rivet holes extending therethrough, a cutting tooth coupled to an upper portion of the cutter body, a feed limiter, and a gullet. The cutter body defines a longitudinal axis extending through the pair of rivet holes and a vertical axis oriented perpendicular to the longitudinal axis. The cutting tooth is set relative to the vertical axis. The plurality of rivets couples the plurality of drive links and the plurality of cutters together.
