gday just wondering about the rakers does this gadget sort them out too. i go threw a lot of chains and like to get my moneys worth. i am using a 20 inch bar to rip posts and 25 inch to butt out brimbel box and brigalow on my place. do you recken this thing is as good as a file. i am never in that much of a hurry to sharpen a chain and if i was proberly should not have a saw in my hand. weather i am under a power line ,cutting fence posts or a customer in town.
