This is a covert operation. A neighbor has declared war upon me without provocation. I have tolerated his ridiculous backyard forestry long enough.

My intention is to use Tordon and reduce his idiot tree-line to a barren desert. I have been learning that I can use a "hack & squirt" method by creating a small cut to the bark and applying Tordon, a latter-day Agent Orange.

But it has to be quiet, so no hacking. I would like to know what is best knife to quietly score some trees.

I assume a simple hunting knife should be enough. But I thought I would consult the wisdom of the internet first.
