I use a shavette I got off of amazon for $14. It is all stainless steel and has pretty nice weight. Best and quickest shave you can do and a fresh blade each time.
For shave prep I use cold water rub and then do a first pass. Then I use an oil to do a second closer pass.
I find that I use the shavette more than the straight razor because it requires stropping and honing to maintain the edge. A fresh Feather brand blade is always super sharp.
