Wondering if anything else has had any consistency problems using the Leaf razor? I've been using it for quite a while now to shave my head, and will get an excellent shave one day, then replace the blades and get completely torn up on the next shave. The only difference is a new blade. I'm using Astra SS. I have noticed sometimes the blades sit kind of lopsided. Wondering if it's the razor? Or maybe an inconsistency in the blade?
