I had it as tight as I could get it with my fingers. I see no way the always keep the razor “even” when doing ATG or XTG passes around nose, on chin, etc. I shaved as I always have; this was the first time it came loose and spun.I'm sorry to hear about the cut! It's because of the long head acting as a better lever arm. If force is applied to right side of the head unevenly (facing the razor), that applied torque can loosen the razor. This probably happened when maneuvering around the nose. If the whole razor is used evenly no such torque is applied and loosening is not possible. A DE experiences about half the torque for the same applied force so it's less likely to loosen under a similar force. I see no need to retire the razor. Simply tight the handle harder and/or use the provided washer to help fill that extra space. We can also send you a washer if you no longer have yours.
I still have the washer, but, one of your videos on YouTube said it was just for shipping and not needed for shaving.
I appreciate the response. Your attention to your customers continues to be the best I’ve experienced in the industry.
