Steve,

One of my brothers (RIP) was an Arborist for a national company.

On the job, he had a couple of files, oil and gas to keep his
chainsaws running. He inspected the saws, before he climbed a tree.

A few times I worked with him as a ground man.

Point: simple tools on the job gets the job done.
