Chainsaw file kit

I bought one o' them they there Stihl Easy File Chainsaw Chain
Sharpening Tool things, and having thought "Oh it'll be carp", changed
my mind very fast. Get one. Very easy to use, very fast, great precision
result each time.

Note: you need a different tool or at least files in the tool for
different sized chains.
