maybe someone can help me. the turning mechanism on the vision razor seems looser now. this morning, i turned it to its most aggressive setting and then after needing to blade buff, turned it less aggressive a bit. the ring that makes the adjustment seemed looser. i tried to then open it back to its most aggressive setting and the gap in the razor would not open up wider, nor would it go to less aggressive. i lightly tapped it against the shower wall and it opened up. this was the first time it did that and now it seems it is standard, that is, i still have to bang it lightly to get it to open up.
what to do?
