Any suggestions on how I can get my $6.75 files (double bevel for square ground chain) last longer? I swear I can't get more than a week out of each one, especially if its a wet week, which this time of year, with all the sweat, everything is pretty much wet all week.
Say I file 4 times a day. Not rocked chains, just touch ups.
They're the ones Madsen's sells.
