Dan Watson (verified owner) –
Excellent for thick brush and brambles.
You’ll also need to buy a LH thread collar nut and rider plate to secure the blade. From what I gather there are two types of rider plate, the older version comes in two parts, but the newer version has those two parts together as one single unit.
