Not sure if you need full or semi chisel?
Full chisel is chain means the cutter blade has more of a straight edge. This allows it to cut faster but if the timber is dirty it may take the edge off faster. Best suited for tree felling or clean firewood work.
Semi chisel means the cutter blade has more of a rounded edge. This allows it to hold its edge better if the timber is dirty. Best suited for dirty timber and stump work.
Remember if its dirty use semi if its clean use full!
