<p>The invention safely guides wood into the tip of a chain saw bar (20) and provides stability (you don't have to wave the tip of the saw around before you start cutting at the tip), gives support and dampening of vibration and sound, eliminates rotational kickback the greatest hazard in using the world's most dangerous tool, and can be attachable and removable from a saw bar, or a permanent part of the saw bar. The invention makes a chain saw an additional tool for tree-trimmers, loggers, homeowners in addition to sawing. With the inventive device on saw you can push or pull wood from a tangled up pile and safely position it for cutting. The inventive device also eliminates cutting in unsteady positions (off-balance, outstretched arms, one-handed, over-reaching). Chain saw with the inventive attachment device (24, 26) provides dynamic tuning to lessen vibration and sound. There is less chain wear, less sharpening, less bar wear, less fatique, less change of Raynauds syndrome, no need for a chain brake to stop rotational kickback, and no need for a banana type bar.</p> |
