Claim Text:
1. A self-adjusting grinding wheel for sharpening a log saw blade while increasing a working lifespan of the log saw blade, comprising: a backing plate to provide support for multiple concentric rings of a face of the grinding wheel to contact the log saw blade; a first concentric ring of the grinding wheel comprising bonded particles or grit of a hard abrasive for grinding a cutting edge of the log saw blade to sharpness; a pressure controlling mechanism on the face of the grinding wheel comprising a second concentric ring of the grinding wheel including a fiber padding for contacting the log saw blade when the first concentric ring contacts the log saw blade; and wherein the pressure controlling mechanism comprising the fiber padding dynamically spreads a contact pressure between the grinding wheel and the log saw blade to maintain a correct sharpening pressure of the first concentric ring against the log saw blade while the log saw blade is in operation.
