A device for sharpening the cutting teeth of a chain saw includes a frame having an upper web and first and second side walls, and an open area defining a sharpening area. The device further includes at least one clamping member operable with at least one of the first and second sidewalls of the frame for securing the frame to the guide bar of the chain saw. The device still further includes a second clamping member movably supported about the frame, which operates to engage a chain saw tooth of a chain and to fix its position within the sharpening area. The second clamping member includes a tooth stop for adjusting the position of the chain saw tooth within the sharpening area. The tooth stop includes a pawl support block and a pawl having at least one working portion engageable with the chain at different positions along a lateral axis of the pawl support block to provide clearance for a sharpening tool within the sharpening area.

A vibrating chain saw sharpener for sharpening a saw chain that includes a cylindrical body portion; a ring portion connected to and encompassing an intermediate portion of the cylindrical body portion; a flange portion extending away from a bottom portion of the cylindrical body portion; and a hand-held power tool removably connected to an upper portion of the cylindrical body portion. Vibrations transmitted from the hand-held power tool to the ring portion are conveyed to the tooth of the chain saw, wherein the tooth is sharpened by the vibrations conveyed thereto.

A chainsaw tooth sharpening tool is presented with a first, e.g., planar, section for reducing a depth gauge of a tooth of the chain and a second section having a geometry for sharpening a cutting corner of the tooth. A chainsaw tooth sharpener apparatus using the chainsaw tooth sharpening tool is also presented. The apparatus comprises a motor for driving a rotative chainsaw tooth sharpening tool to be mounted thereto according to a rotation axis, a base to hold a tooth of a chain to be sharpened, and adjustment means to adjust the motor relative to the base. The adjustment means are adapted to adjust the motor relative to the base according to at least two of a) a depth adjustment, b) a longitudinal adjustment relative to the chainsaw tooth, and c) an angular adjustment relative to the chainsaw tooth.

A portable sharpener for chains of chainsaws comprising sharpening means (2) and a coupling device (3). The sharpening means (2) are configured to sharpen the teeth (102) of a chain (101) of a chainsaw. The coupling device (3) supports the sharpening means (2) and is configured to be reversibly constrained to the chainsaw. Furthermore, the coupling device (3) comprises a support structure (4) which has a first plate (4a) adapted to be arranged parallel to a main extension plane of a chain guide bar (100) of the chainsaw and a second plate (4b) configured to abut against the bar (100), in such a way as to be at least partly interposed between the bar and the chain (101). The first and the second plate (4b) are arranged substantially in an L-configuration. The coupling structure further comprises one or more attachment members (5) applied to the first plate (4a) and configured to constrain the support structure (4) to the bar (100) of the chainsaw.

Disclosed is a chainsaw workbench for safely controlling a chainsaw during sharpening of blades thereof. The chainsaw workbench includes a base placed on a fixed support; a first elevation platform attached to the base to rest the handle of the chainsaw; a second elevation platform attached to the base to rest the handle of the chainsaw; a first mount extending upwards from the base along the edge of the first elevation platform; and a second mount extending upwards from the base along the edge of the second elevation platform, wherein the distance between the first mount and the second mount is sufficient to receive the blade of the chainsaw; wherein the chainsaw blade rests on the first mount and the second mount. Further, the chainsaw workbench includes a tool box placed on the base to store tools. Furthermore, the chainsaw workbench includes a first screw to tight the first mount; and a second screw to tight the second mount.

A chain saw guide bar mounting device for facilitating maintenance of a cutting chain includes a first plate that is configured to mount to a support structure. A second plate that is coupled to the first plate extends longitudinally from proximate to a first end of the first plate. Each of a pair of couplers coupled to the second plate is configured to couple to a respective penetration that is positioned in a guide bar of a chain saw. A bracket, which is slidably coupled to the first plate, is positioned between the second plate and a second end of the first plate. A second rod is selectively couplable to the bracket. A hub is axially positioned on and rotationally coupled to the second rod. The hub is positioned to rotationally couple to a cutting chain that is positioned on the guide bar to position the cutting chain for maintenance.
