Bontrager NCS fenders/mudguards have a clever trick up their stays: instead of trimming them to make them fit your bike properly, you adjust the length of the stays by sliding the two parts up or down as necessary, using the built-in clamps to then lock them in place. 

The clue’s in the TLA: NCS stands for No-Cut Strut. It’s so much less hassle than hacksawing or dremelling that it’s amazing to me that so many of even the best fenders/mudguards don't work like this.
