The real trick is to lube and to keep the shoe on the work.
This means push against the work as it saws. Using the correct pitch
blade is important - e.g. the 3 tooth in the metal at a time rule is
kept here if possible.

And yes - I have a 18" blade for limb cutting - it is green after all -
and it
slices the end of the Christmas tree every year. Don't remember ever
doing any sawing on a tree, but heck - a long extension cord and a saw
up the
tree might be nicer than a chain saw in the same hands.
