Embodiments herein describe presets for saw chains comprised of one or more rivets that are coupled to a tiestrap. Each rivet may further comprise a central flange and a hub protruding from opposed sides from the flange. In some embodiments, the hub may be non-concentric from the flange, and the flange may be non-circular, such as ovoid or cam-shaped. In some embodiments, various portions of the flange, rivet, and tiestrap may be selectively hardened to various degrees of hardness, depending upon their location and usage. In some embodiments, the rivets may be prevented from rotating with respect to the tiestrap using a brazing process, and may be configured to facilitate such processes. Other embodiments may employ a non-circular hub. Still other embodiments may use a low-temperature process for soldering that does not affect the hardness of the tiestrap or rivet.

A log splitter where splitting force is generated by storing kinetic energy in a rotating flywheel. Rotational energy is converted to splitting force by means of a rack and pinion, which is coupled to the flywheels through a belt-driven clutch system. A belt rests around a driven sheave and a drive sheave. An idler pulley tensions the belt, causing the driven pulley to rotate. The idler pulley is attached to an actuation handle causing the idler to lock, by means of a latch, until the operator disengages the pulley, or until a component mounted to the rack forces the latch to disengage. The rack remains engaged to the pinion by a bearing mounting system. A spring bumper may be placed at the end of travel so that at the end of the stroke, the ram mechanism compresses the spring, and uses stored energy to reverse the ram, pinion and sheave.
Embodiments herein provide a modified pitch sprocket to provide an orientation of a saw chain link, such as a cutter link or drive link, with respect to the direction of travel of the link, as it traverses the sprocket that is different than the orientation of the link as it traverses a straight portion of the guide bar. In some embodiments, the modified pitch sprocket may orient the cutter link to provide radial extension for a depth gauge of the cutter link relative to a cutting element of the cutter link. This may facilitate shaping of the depth gauge and/or cutting element, such as by a sharpening element, as the cutter link traverses the sprocket.
Embodiments herein provide formed wire tie strap for a saw chain. Embodiments also provide a saw chain including one or more formed wire tie straps.

The conditioning portion of the drive link may contact the sharpening element in a third contact region that includes at least a portion of the gap between the first and second contact regions.
Embodiments herein provide an involute slicer having a body portion and a blade coupled to the body. The involute slicer may further include an anvil to provide structural support to a workpiece. The blade may rotate about an axis. As the blade rotates, the blade may pass next to the anvil, thereby cutting the workpiece. The blade may include a cutting edge with a radius that increases from a proximal end to a distal end of the cutting edge. For example, the cutting edge may have an involute shape. The involute shape of the cutting edge provides a radially expanding cutting edge as the blade is rotated. In some embodiments, the blade may include a plurality of cutting edges, such as two cutting edges.
Embodiments herein provide systems, devices, and methods for splitting logs, wood, and other materials. A splitting device safety feature is disclosed, the safety feature comprising a safety locking mechanism that generally requires operation or activation by at least one hand of a user and an activation mechanism which generally requires activation or use with the other hand of a user. Both mechanisms are required to be activated, each by at least one hand of a user, in a simultaneous manner in order to activate at least some features. For example, a safety lock out mechanism is provided that prevents or blocks the activation of the device from initiating log splitting processes. Therefore, two distinct features requiring the use of at least one hand of a user are required to be activated or operated in order to perform log splitting functions.
