The Excalibur club is a club that originates from Badger and blade, and basically it consists of a bunch of guys challenging the stigma that a blade should be binned after 3 shaves. It encourages people to shave and replace blades by feel rather than a fixed time, and discover the different properties of different blades as well as how those properties affect lifespan. Its a huge case of YMMV. Ive gotten about 15 shaves out of a Derby before it needed replacing and about 20 out of a lion, but some guys have gotten 125 shaves out of a blade!!! Its not a case of saving money and using less blades, its about finding out how long different brands last for you and learning how to tell when they need replacing, and its a journey id highly recommend to everyone, even those not members of badger and blade.
