Dan,
One of the best tools for cutting down your bamboo would be a reciprocating
saw. Power tools are almost always preferable to hand tools if you have much
bamboo to deal with. Most any blade will do for the saw but the best one is
called the Ugly Blade, which I get from Home Depot (other stores probably carry
them too).
Where in the Bay Area are you. I am in El Sobrante.
