The theory is that full chisel depends on a single point of cut that needs to be kept sharp and the semi chisel has a rounded point of cut meaning the cutting load is spread a little around its circumference and will therefore take a little more abuse then the full chisel before it craps out!

 

Novices also find semi chisel easier to sharpen than full chisel down to the design of the cutter and the system being more forgiving.

 

For the record, I have tested a new Microlite Pro bar and 95VPX chain against a Stihl full chisel on a full kerf bar and the Oregon system came out 15% faster - and that is what their adverts also claim! It is a fast cutter but probably not up to the duress of pro cutting all day long!

 

Anyway - you are both right - keep the peace:001_rolleyes::lol:

Ditto - a full speed cut into earth will knacker both - but the fine point on a full chisel is more delicate than the slightly rounded one on micro chisel when it comes to a minor brush with grit...
