Hyundai Grade A+ HYBC5080AV Anti-Vibration Grass Trimmer / Brushcutter

  

The 3 tooth blade would be used for brambles etc and the 8 tooth blade for thicker wood like growth where a sawing action is required. The nylon string is best used on grass and next to hard obstacles, with the cutting blades ideally used on thicker weeds, brambles and scrub.
