I'm using a chain saw more now. I got four or five chains, some dull, and
some unfindable. I have a Sears sharpener that has an alignment jig. I
have kind of gotten the hang of it, and it seems to work pretty good. But,
we're going to go up and cut some wood, and I think if I can figger out the
angles, a pocket hand file would be infinitely easier to use in the field.

Any pointers, tips, or easy to follow sites?

What about a battery Dremel type sharpener?

I'm looking for quick and easy and portable.
