I think you already got plenty of answers here. So I'll anwer a different part.

There's no need to keep your razor oiled or vaselined if you're using it every few days. I have razors that sit for weeks (sometimes months)between shaves, and are no worse for wear. All my razors were polished prior to honing, which does leave them with a very thin invisible coating of protectant behind. The only razors that I've seen rust or corrosion start on or get worse, was razors that never got polished. Anyhow, I guess that might save you a few minutes.
