Coalatree Haswell Survival Knife w/ Leather Sheath

I wondering about how to care for it. I've read not to leave it in the sheath and that it needs to be oiled to keep from rusting. So my questions are: I will probably only use one season a year. So I'll store it for long periods of time. What is good way to store it out of the sheath? Also, in regards to oiling it, how often, and by which means, shall I oil it?

I absolutely adore hammering directly on my tip ^_*
