ok glenn,

there is an 8 tooth non-reversable steel bade (diy sharpening) may be
the better one for you depending on sapling you could need the saw
toothed blade as well? this 8 tooth blade is app' 250mm across so
probably not going to be much use on machines under maybe 25+cc? i use
it on my 27cc model but only for light brush work say woody weeds and
cane type grasses.

dependig on how much work you have maybe you need to look at machines
in the 40cc range?



snipped
With peace and brightest of blessings,

len
