I think I'm the opposite. I learned that my first razor that I got that wasn't as sharp as it should have been now that I've honed and shaved with 2 razors I recently picked up (Gold Bug and Dubl Duck Satinedge.)

The Bug was a MUCH better. Cleared my cheek off with the slightest pass. Then I got my DD in the mail...sanded the blade and sharpened her up to try it out and YOWZA! That baby was SCARY sharp! (Got a little cut to prove it )

So I guess I have come to appreciate a scary sharp razor...

As far as dulling it down...maybe running the blade over something to take the edge down a bit? An eraser, or cork maybe? Never tried it tho

Not sure why someone would prefer a duller edge, unless they just want to shave fast and sloppy without slicing their face up
