How to Sharpen the Grass Blade on a Husqvarna 525RX Brushcutter

New 45 acre property I am working on. It is located up the hill from the old 75 acre sheep ranch I had previously worked on. Lumberjackin' to make the land more open, healthy sustainable and fire-resistant. Below are the links to my lumberjack equipment and land management techniques:

Carhardt makes excellent double front, logger pants with suspender buttons. They also make decent suspenders. This would be a perfect pant/suspender set up for a beginner. After you know what you are doing you can upgrade to Better S-Penders.
