My first straight razor just arrived in the mail on Friday - a Thiers-Issard from Vintage Blades, LLC. It came honed to shave-readiness by Lynn Abrams. I'm trying to figure out what kind of stone I should get to to maintain the edge. A barber's hone? A Norton 4k/8k? I don't have an aspirations of restoring razors or anything like that. I just want to start good maintenance habits right out of the gate. Any guidance would be much appreciated.

Also, do I need to oil my razor after each use? If so, what product(s) does the group recommend.
