astra 2 - 3 times max. i know it's done when it hurts my face. that's usually midway through shave 3.
Am I the only one to use a shaving log spreadsheet for storing such important data?
I just keep the blade wrapper in the drawer with a pencil. Hash mark per shave. I get 268 shaves per pencil sharpening if I make short, one-pass hash marks. Pencil's about 1/6 gone. No pressure-I don't want to break the lead. Have hardly used the eraser.
