I just used Mine Today, with a Feather blade and 2012 "NEW STYLE" Thicker Weber Classic Polished Handle, What an awesome Shave, and that my friend is what its all about, The shave
I know there not made of brass but i have had mine for close to two years now and it still looks new. I just like to replace the handles to heavier ones and prefer Solid Stainless Steal Handles.
Most Brass Razors dont survive a fall without some sort of defect, TTO will usally fall out of alignment, Open combs will have bent teeth if dropped . Just treat your EJ with care and it should last you a life time
If you take care of it, there is no reason why it won't last well beyond your lifetime. If problems do occur, replating can be an option if it eventually becomes a collector or heirloom object for someone.
Correct me if I'm wrong, but I don't believe zamak can be replated. If I'm wrong, please tell me who replates it.
