CHAIN SAW SHARPENING GUIDE Abstract of the Disclosure A chain saw sharpening guide is comprised of a relatively thick rigid and rugged plate metal member which has a threaded bore to receive a micrometer-type height adjustment screw to give an accurate indication of the raker also called depth gauge) tooth on the chain. The metal plate member is elongated and has a length spanning at least the distance between at least three consecutive teeth on the chain saw. A cut-out or notch formed on one long Aide of the plate member permits the plate to rest on two consecutive teeth on the same side of the chain saw with the intervening tooth on the opposite side projecting upwardly into the notch or cut-out space so that the measurements of depth of cuts skips the tooth on the opposite side of the chain and uses for the depth gauge measurement the two teeth on the same aide of the chain. A sunburst angle gauge from 0 to 35 degrees (in 5 degree increment) for either the left or right tooth angles is formed in the top surface. A pivoted bar is secured to the gauge by n knurled nut to allow measurements to be made of the length of the cutter teeth.
