This is a great tool to have and use as a guide in the shaping of your chainsaw chain grinding wheels and it's also handy to have to use to check the size chainsaw files with the file size holes, check the angle of your chain cutters, chain pitch identification with the 3 rivet measurement guide built in on the tool (the distance between any 3-rivets divided by 2 = the pitch of the chain), depth gauge settings and the radius of your wheel.
