  • removing tree stumps

  • breaking up brown-rock, blue-rock etc in quarries
  • digging trenches even through rough terrain
  • breaking up tarseal


The DiggerKnife is made from Hardox 500, ensuring the best material possible so that the DiggerKnife is the strongest it possibly can be and will not bend, chip or break.
