Welcome to the straight shaving game!

From advice I've seen in another thread somewhere, if it's professionally honed you'll be able to shave with it right of the box, but after that first shave you'll need to strop it. As I understand it, the blade will need a good stropping before each shave but especially with newbie technique being harsher on the blade than refined technique.

My guess is it would be possible to shave that long without stropping, but it would be terrible for your face and razor. My advice: wait for the strop, your blade and face will thank you.
