I just dropped my Ikon SK9 using it during my shave. I'm depressed and somewhat irate at my stupidity; I should've dried my hands before handling it. My only consolation is that it can handle being dropped on a procelain sink, I hope.
It should be able to handle being dropped into a sink. A base metal/chrome plated new razor wouldn't crack (I don't think) and a vintage razor, many years old, was probably dropped sometime in its past--and survived. So relax.
I just had the same thing happend with my new Muhle Grande. Except it dropped on my tile floor and the chrome chipped off the top. Third shave...oh well.
