How many of you wear your chaps to the bar? No no- really. Per sharpening the chain on the saw, we all know that a file on site is the best thing. But getting to the point when most fols take the chain in to the shop to get the angle correct again, I was looking to get a similair device for the bench so I wouldn't hafta make the day trip into town. Can anyone point me in the right direction as to what a device is called and where I might get one...............
