I've made a couple Vic for family, one in Yew, one in blackwood and they look great but I have the same water ingress reservations re wood. The most common is to fit Gillette Mach 3 blades though I use Fusion blades and bought a couple of kits from TR which they got from the US for me as I can't find them in the UK. I have one of these prepared and glued in to a bit of tru-stone for my own use but can't get the matching brush blank so might need to re-think that one.
I would also always go for chrome over gold finish but thats personal preference.
Love the idea of the birhdate coin Phill, I'm going to nick that
