The simplest way to finish a stock is watcos danish oil. I would use the natural color instead of one of the ones with stain mixed in. It will darken the wood a fair amount and bring out its natural color.
Pretty simple, sand the wood down to 150 grit, pay close attention places where the end grain is exposed. Shake the can of finish really well, and using an old T shirt or some other kind of rag start wiping on a heavy coat. Wipe it on until its uniformly wet and no more is soaking in. Wring out the wrag and wipe it down again so that there is just a thin layer on the wood and no runs. Leave it to dry, depending on the wood and the humidity it could take anywhere from an hour to a day.
LIGHTY (don't put much more effort into it than wiping the finish on, just scuff it up, only sand heavily on spots where the grain has raised) sand the wood down again with 320 grit paper, spend most of your time on the end grain it has a tendency to raise a little.
Wipe on another light coat of watcos, and leave it to dry.
If the grain is raised or it doesn't seem to be taking it evenly, lightly sand again with 400 grit or more 320. And wipe on another coat, then let it dry.
This time you should be able to buff it out with a dry cloth and it should look pretty nice. You can put more coats on if you want, but 3 should offer pretty good protection.
Then maybe once a year wipe it down with another coat, you'll have plenty left from the first can.
It sounds kind of involved but its just a matter of sanding and wiping the stuff on. Clean up is easy, you don't need any solvents, and the results are good. The color change in the wood is pretty consitent from one type to another. You get a nice penetrating finish that will repel water and gives a little bit of a shine. Its cheap too
