between the second jaw 14 and the face of the cutting edge 22 show nonconformity the cutting edge 22 can then be filed using filing techniques known in the art until the angle of the cutting edge 22 matches the gauge angle u03b8 of the second jaw 14 wherein the entire cutting edge 22 mates against the second jaw 14 along its angled edge the present invention provides a user with a convenient and inexpensive tool for measuring the quality and dimension of chainsaw teeth along a chainsaw chain the shortest top plate can be measured and if desired can be carried through each top plate along the chainsaw length to ensure uniformity the cutting edge angle can further be inspected and checked against a given angle which is unique for the specific measuring tool different angle measurements may be provided on separate tools for a desired chainsaw angle the locking means on the measuring tool allows each top plate to be compared to one another without changing the measured distance when moving from one chain tooth to another the goal of the present invention is to reduce maintenance costs and increase time intervals wherein the chain must be professionally serviced to this point the instant invention has been shown and described in what is considered to be the most practical and preferred embodiments it is recognized however that departures may be made within the scope of the invention and that obvious modifications will occur to.
