Well USPS finally decided to show up so my new kit from SRD is here(YAY). Just got a few questions I didn't think about before now

1. This kit came with Razor oil. Is this something that needs to be applied before its put away at the end of a shave, or is it more for if the razor is not going to be used for a few days or more?

2. I've heard that for the first shave with a properly honed razor you should just shave and not strop until the second use, is there merit in this?

3. For the strop, I normally use neatsfoot oil to condition the other leather goods I work with, will this oil interfere with the razor during stropping or is it safe to use every once and awhile to keep the strop in good shape?
