I've got uncontrolled bamboo forest with stalks rising to approx 40-50
ft (some black, some green in color). Stalks have a diameter of approx.
2" as the base, max. (I would guess).

Is it best to cut the bamboo stalks with a BYPASS looper or with an
ANVIL looper? Are there any recommendations? I'm looking at Fiskars
and Gardena brands (amazon.com).

I've been using an anvil looper approx. 24" in length but the blade is
now very dull and can't be easily sharpened, nor replaced.

My guess is that bypass loopers must be much more robust than anvil
loopers as the two blades can get pushed apart and the slippery bamboo
get stuck between the blades as they "bypass" each other. Therefore I'm
gravitating towards an anvil looper.

Thanks much for your advice!
