I mentioned this in a previous thread and 4 shaves seemed to be about average. When i was cart shaving i just kept using until the blade felt dull. So i thought i'd try this approach with my gems, so after reaching shave number 8 on one blade i'm still getting a nice close shave with no stinging from the alum. certainly much better than the 3 shaves fron DE blades i've tried. So m going to keep going until the blade tells me its had enough.
