I would agree that SRs are possibly the greenest option. BUT, here's a radical thought... when the plastic handles are beyond repair, do they have to be replaced? A Kamisori has no 'handle' to close into. Do SRs really have to have them? Would you use your SRs without handles? A bare blade SR can be a beautiful thing on its own, but the scales make a complete razor package, but they don't actually make any difference to the shave. We all like our razors to look as good as possible don't we?

Am I being green by posting this response? Those already on the thread may log back on to read the updates. Am I responsible for the power that takes?
