I want to put together a kit/toolbag of things to have available when removing/fixing girdling roots. I've done quite a bit already by using whatever tools I have available to me- pruners (which get sharpened a lot!), hand saw, then the rest are crude tools that shouldn't be near the base of a tree (hammer...screwdriver...).
I'm thinking having a chisel or 2 or 3 available would be nice. And 2 brushes...a big one to move handfuls of soil at a time, and a smaller more precise one for cleaning out crevices between roots so I can fit my pruning tools in there.
Are there some obvious things I am missing here? What size/shape chisel would be best? I'm thinking something short would be easier to handle. Also, most chisels are shaped like this: ] on the end...and maybe one shaped like ) would be better?...or like the ] but with rounded edges?...then, I've seen some that are scooped (like if you cut a drinking straw lengthwise)...
Any thoughts? What do you use?
