Do you file depth gauges on safety chain?

I like the way you say "beat the grass off cleaner"

My string trimmer can really plow through the grass, but the string is round, and is probably the dullest shape possible?

Even a blunt edge would have corners that would help make it sharper.

Interestingly, I ran out of string for my trimmer and bought new line that turned out to be square !!

It works Way Better !!!

My chain link fence used to eat up all kinds of blunt round line because I had to rev the snot out of my trimmer to "beat the grass off".

With the square line, my rpms are Way Slower with the "sharpened corners" to cut through the grass, so the line just rubs on the wire fence instead of being cut.

Used for smaller trees on the ground; easier on cutters back. I think this one is missing a guard.

Bow Bar???? What is the purpose of a bar like this

Can any one tell me exactly what a bow bar is used for, are they better or worse than the normal bars found on chain saws for cutting. The only thing I know about a bow bar is the pulp cutters down south like them. The reason for the question is I recently bought an old Homelite gear drive...
