Sorry for the late response, but I would say that since I dont personally use the shavettes on just beards but instead mostly on necklines and around the ears, that I could get around 5 customers worth of shaves with a double edge blade, and more than double that with a injector type or feather artist blade. I prefer those blades, and I have every shavette you can purchase. I tend to use the Hess Ezy shave razor and the Charles Monsieur razor the most which both use personna injector blades. I like the weight they have and they are built much better than most double edge type blade razors. If I do a face shave, I always use my feather artist dx razor.
