The combi steel has a safire cut on 2 sides (fine grit) and is polished on the other 2 sides. It should work well for you. The steel comes with a plastic sheath that will protect it. I would also suggest you bring it to work in a cheap knife bag like this:http://www.chefknivestogo.com/ch8pcknro.html
If you want to clean the rod I would suggest hot sopy water and a sponge. That's it.
