I have a Merkur Futur with uneven blade gap. In my case, the blade runs parallel both sides, but one side has more exposure than the other. Initially this put me off and I rarely used it. However, I am now beginning to quite like it ... The gentler side is ideal for the tricky chin and moustache areas and the more fierce side is great for mowing the easier bits. Paired with a feather blade it provides at least a DFS every time. I wondered whether anyone else has experienced this? Equally I wonder whether this sort of "defect" was the inspiration for the ikon ...
