What I do is buy "duplicate" tools for some things. Like I have a hammer in the house and another hammer in my shed. So if I am in the house and need a hammer, well there it is.
And I do the same with my chainsaw stuff. I have a separate large tool box for just chainsaw stuff. In this tool box is *everything* I need for my chainsaws including tools, spare chains (in baggies), files, depth gauges, magic marker, old toothbrush for cleaning, and a few spare parts for saws.
Some of the tools in my chainsaw tool box are "duplicates", meaning that I have duplicates of the same tools elsewhere. By having duplicates in the tool box, I don't ever need to remove any tools from the chainsaw tool box when doing any other work. So these tools stay in the chainsaw tool box! And when I grab the chainsaw tool box, I know everything I need is in there.
So costs a bit to get duplicate tools, but saves a lot of time hunting and searching for this or that. Plus you will not be a zillion miles up in the woods and suddenly need a certain tool and realize you did not bring it with you.
