Hey all,

Today has been my first straight razor shave. I bought a Ustura shavette with disposable Derby single blades. As a beginner, I felt more comfortable with a disposable system that was lower in maintenance. I've cut myself quite a bit, but it's only day 1 so I'm not too discouraged. (I'm still used to a Mach 3 / Quattro razor and the pressure involved).

With the Derby disposables, should 1 blade be sufficient for a morning shave, or is it wise to replace the blade halfway through?
