what else to do on lunch break?
this is the saw that i so glowingly recommend...

this is a close up of the chain:

this is a relatively new chain for my 16-inch bar and the dogs arent filed yet.. i wont file the dogs until after it wears more. at most i file them down to the level of the non-cutters, then when that chain wears out i buy new.
if you are going to try this do so at own risk, i dont feel like being sued. use a flat file and do a little at a time on each dog. do it conjunction w/ a good sharpening on the cutting teeth. if you file too far (like all the way down) the chain will grab wood too hard and it is really not safe.
